[0079] Now will refer to embodiment in more detail, the example of embodiment is shown in the accompanying drawings, wherein the same reference numerals refer to the same elements throughout the present disclosure, and may not provide its repeated description. In this respect, the current embodiment can have different forms, and should not be interpreted as being limited to the description set forth in this article. Therefore, the embodiment is described only by reference to the accompanying drawings to illustrate the various aspects of the current description. As used in this article, the term "and / or" includes any combination and all combinations of one or more associated listed items. When the expressions such as "at least one (kind / person)", "one (kind / person) in ...", "selected from" and "selected from ... among" are before or after a column of elements, what is modified is the whole column of elements, rather than the individual elements in the modified column. For example, throughout the present disclosure, "at least one (kind / person) in a, b and c" indicates only a, only b, only c, both a and b (for example, a and b at the same time), both a and c (for example, a and c at the same time), both b and c (for example, b and c at the same time), all a, b and c or its variant.

[0080] Unless otherwise defined, all chemical names, technical terms and scientific terms and terms defined in common dictionaries should be interpreted as having a meaning consistent with the context of the relevant field, and should not be interpreted in an ideal or overly formalized sense. It will be understood that, although the terms first and / or second etc. can be used in this article to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish an element from another element. Therefore, without departing from the teaching of the present disclosure, the first element can be referred to as the second element. Similarly, the second element can be referred to as the first element.

[0081] As used herein, singular forms such as “a,” “an,” and “the” are intended to include plural forms as well, unless the context clearly indicates otherwise.

[0082] It will be further understood that when the terms “comprise / comprises / comprising,” “has / have / having,” and / or “include / includes / including” are used in this specification, it indicates the presence of stated features, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof.

[0083] As used herein, the terms "use / using / used" may be considered synonymous with the terms "utilize / utilizing / utilized," respectively.

[0084] The term "may" will be understood to refer to "one or more embodiments of the present disclosure," some of which include the described element, and some of which exclude the element and / or include alternative elements. Similarly, alternative language such as "or" refers to "one or more embodiments of the present disclosure" that each includes the corresponding listed item.

[0085] It will be understood that when an element is referred to as being "on," "connected to," or "coupled to" another element, the element may be directly on, directly connected to, or directly coupled to the other element, or one or more intervening elements may be present. When an element is referred to as being "directly on," "directly connected to," or "directly coupled to" another element, there are no intervening elements.

[0086] For ease of description, spatially relative terms such as "below," "below," "down," "above," "up," "bottom," and "top" may be used herein to describe the relationship of one element or feature to other elements or features as shown in the figures. It will be understood that the spatially relative terms are intended to cover different orientations of the device in use or operation in addition to the orientations depicted in the drawings. For example, if the device in the drawings is flipped, an element described as being "below" or "below" other elements or features will be oriented as being "above" or "on" the other elements or features. Thus, the term "below" can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein should be interpreted accordingly.

[0087] As used herein, "consisting essentially of" means that any additional components do not substantially affect the chemical, physical, optical, or electrical properties of the semiconductor film.

[0088] In the present disclosure, "does not include (or does not contain) a "component" or any "component", "excludes (or removes) a "component" or any "component"" and / or "does not contain a "component"", etc. means that the "component" is not added, selected or used as a component in the structure / composition, but due to other impurities and / or external factors, the "component" may still be included in an appropriate amount.

[0089] Furthermore, in this specification, the phrase "on a plane" or "plan view" means observing a target portion from the top, and the phrase "in cross section" means observing a cross section formed by vertically cutting the target portion from the side.

[0090] The expression “the composition and / or the optically active layer includes a first compound represented by Formula 1” as used herein may be understood as “the composition and / or the optically active layer includes one kind of the first compound represented by Formula 1” or “the composition and / or the optically active layer includes two or more different kinds of first compounds each represented by Formula 1”.

[0091] The expression “the composition and / or the optically active layer includes a second compound represented by Formula 2” as used herein may be understood as “the composition and / or the optically active layer includes one kind of the second compound represented by Formula 2” or “the composition and / or the optically active layer includes two or more different kinds of second compounds each represented by Formula 2”.

[0092] The expression “the composition and / or the optically active layer includes the third compound represented by Formula 3” as used herein may be understood as “the composition and / or the optically active layer includes one kind of the third compound represented by Formula 3” or “the composition and / or the optically active layer includes two or more different kinds of third compounds each represented by Formula 3”.

[0235]

[0237] The third compound

[0238] The third compound may be represented by Formula 3. Therefore, the third compound is obviously (and / or should be obvious to a person skilled in the art (e.g., upon observation)) different from the fullerene compound and the subphthalocyanine compound (e.g., each of the fullerene compound and the subphthalocyanine compound). The deposition temperature of the fullerene compound is about 400°C or higher, for example, in the range of about 400°C to about 500°C. Therefore, when the fullerene compound is utilized, high temperature deposition is required, and therefore, the fullerene compound is not suitable for use as a material for an optoelectronic device. For example, in order to ensure processability, the third compound may have a deposition temperature of less than about 400°C. Therefore, when the third compound is utilized instead of the fullerene compound, deposition may be performed at a relatively low temperature, and therefore, the optoelectronic device may be manufactured more easily.

[0239] For example, the deposition temperature of the third compound may be about 350°C or less, in a range of about 100°C to about 300°C, or in a range of about 200°C to about 300°C.

[0240] The third compound may absorb light having a wavelength in a range of about 400 nm to about 1,000 nm.The third compound may be used to absorb blue light, green light, red light, near infrared light, and / or any combination thereof.

[0243] R 21 To R 26 Can be independently selected from:

[0244] hydrogen, deuterium, -F, -Cl, and cyano;

[0245] C unsubstituted or substituted by deuterium, -F, -Cl, cyano or any combination thereof 1 -C 10 alkyl;

[0246] Unsubstituted or substituted with deuterium, -F, -Cl, cyano, -CF 3 or any combination thereof substituted with C 6 -C 10 Aryl; and

[0247] Unsubstituted or substituted with deuterium, -F, -Cl, cyano, -CF 3 or any combination thereof substituted with C 6 -C 10 Heteroaryl.

[0248] In one or more embodiments, the HOMO energy level of the third compound may be in the range of about -7.4 eV to about -6.5 eV. For example, the absolute value of the HOMO energy level of the third compound may be in the range of about 6.5 eV to about 7.4 eV. For example, since the HOMO energy of fullerene C60 is -6.4 eV, the third compound may not be a fullerene compound.

[0249] In one or more embodiments, the LUMO energy level of the third compound may be about -3.5 eV or greater. For example, the absolute value of the LUMO energy level of the third compound may be about 3.5 eV or less. For example, since the LUMO energy of fullerene C60 is -3.7 eV, the third compound may not be a fullerene compound.

[0250] In one or more embodiments, the third compound may be at least one selected from Compound C1 to Compound C15:

[0251]

[0252] The third compound included in the composition described herein may be the same as the third compound included in the optoelectronic device, electronic device, or electronic equipment described herein, and therefore, a description of the third compound will not be provided in the description of the optoelectronic device, electronic device, or electronic equipment.

[0253] Because the composition includes each (e.g., all) of the first compound, the second compound, and the third compound, an optically active layer including each (e.g., all) of the first to third compounds can be easily manufactured in a one-chamber process by vacuum depositing the composition.

For example, the object 600 may be a finger of a user of the electronic device. The light reflected from the object 600 may be incident on the optoelectronic device 30. Therefore, the optoelectronic device 30 may be used as an optical sensor, and this aspect is described in more detail herein.

[0263] The first covering layer may be arranged outside the first electrode 110, and / or the second covering layer may be arranged outside the second electrode 150.

[0264] Light generated in the emission layer 130 of the light emitting device 10 may be emitted toward the outside through the first electrode 110 (which may be a semi-transmissive electrode or a transmissive electrode) and the first cover layer. Light generated in the emission layer 130 of the light emitting device 10 may be emitted toward the outside through the second electrode 150 (which may be a semi-transmissive electrode or a transmissive electrode) and the second cover layer.

[0265] According to the principle of constructive interference, the first cover layer and the second cover layer can improve the external emission efficiency, thereby improving the light emission efficiency of the light emitting device 10 and thus improving the light emitting efficiency of the light emitting device 10.

[0446] quantum dots

[0447] The emission layer 130 may include quantum dots.

[0448] The term "quantum dot" as used herein refers to a crystal of a semiconductor compound, and may include any material capable of emitting light at one or more suitable emission wavelengths depending on the size of the crystal.

[0449] The diameter of quantum dots can be, for example, in the range of about 1 nanometer (nm) to about 10 nm. Unless otherwise defined, in the present disclosure, the term "particle size" or "quantum dot size" refers to the average diameter if the particles or dots are spherical (e.g., when the particles or dots are spherical), and refers to the average major axis length if the particles or dots are non-spherical (e.g., when the particles or dots are non-spherical). The particle size or dot size can be measured by using a particle size analyzer (PSA) or from a transmission electron microscope (TEM) image or a scanning electron microscope (SEM) image. "Particle size" or "dot size" is, for example, an average particle size or an average dot size. "Average particle size" or "average dot size" refers to, for example, a median particle size or dot size (D50), which refers to the diameter of particles or dots with a cumulative volume of 50 vol% in a particle size or crystallite size distribution. As another method, the measurement and data analysis can be performed using a dynamic light scattering measurement device, the number of particles or dots can be counted for each particle size or dot size range, and then the average particle size or average dot diameter (D50) can be obtained therefrom by calculation. In some embodiments, the average particle size or average dot diameter (D50) can be measured by using a laser diffraction method. If the measurement is performed by a laser diffraction method (for example, when the measurement is performed by a laser diffraction method), for example, the particles or dots to be measured can be dispersed in a dispersion medium, and then can be irradiated with ultrasonic waves of approximately 28 kHz at an output of 60 W using a commercially available laser diffraction particle or dot size measurement device (for example, MicrotracMT 3000), and then the average or dot diameter (D50) can be calculated based on 50% of the particle or dot diameter distribution in the measuring device.

[0450] Quantum dots can be synthesized by a wet chemical process, a metal organic chemical vapor deposition process, a molecular beam epitaxy process, or any process similar thereto.

[0451] The wet chemical process is a method that includes mixing the precursor material with an organic solvent and then growing the quantum dot particle crystal. When the crystal grows, the organic solvent naturally acts as a dispersant coordinated on the surface of the quantum dot crystal and controls the growth of the crystal, making it possible to control or select the growth of quantum dot particles through a process that is less expensive and easier than vapor deposition methods such as metal organic chemical vapor deposition (MOCVD) or molecular beam epitaxy (MBE).

[0452] Quantum dots may include: Group II-VI semiconductor compounds; Group III-V semiconductor compounds; Group III-VI semiconductor compounds; Group I-III-VI semiconductor compounds; Group IV-VI semiconductor compounds; Group IV elements or compounds; or any combination thereof.

[0456] Examples of Group I-III-VI semiconductor compounds are: ternary compounds such as AgInS, AgInS 2 、CuInS、CuInS 2 、CuGaO 2 、AgGaO 2 and / or AgAlO 2 etc.; quaternary compounds such as AgInGaS and / or AgInGaS 2 etc.; or any combination thereof.

[0458] Examples of Group IV elements or compounds are: single elements such as Si and / or Ge, etc.; binary compounds such as SiC and / or SiGe, etc.; or any combination thereof.

[0459] Each element included in the multi-element compound such as the binary compound, the ternary compound, and the quaternary compound may be present in the particle at a substantially uniform concentration or a non-uniform concentration.

[0460] In one or more embodiments, the quantum dot may have a single structure in which the concentration of each element in the quantum dot is substantially uniform, or may have a core-shell dual structure. For example, the material included in the core and the material included in the shell may be different from each other.

[0461] The shell of a quantum dot can act as a protective layer to prevent chemical denaturation of the core to maintain semiconductor properties, and / or act as a charging layer to impart electrophoretic properties to the quantum dot. The shell can be single-layer or multi-layer. The interface between the core and the shell can have a concentration gradient, in which the concentration of the element present in the shell decreases toward the center of the core.

[0462] Examples of quantum dot shells are oxides of metals, metalloids or nonmetals, semiconductor compounds or combinations thereof. Examples of oxides of metals, metalloids or nonmetals are: binary compounds such as SiO 2 、Al 2 O 3 、TiO 2 、ZnO、MnO、Mn 2 O 3, Mn 3 O 4 , CuO, FeO, Fe 2 O 3 , Fe 3 O 4 , CoO, Co 3 O 4 and / or NiO, etc.; ternary compounds such as MgAl 2 O 4 、CoFe 2 O 4 、NiFe 2 O 4 and / or CoMn 2 O 4 etc.; or any combination thereof. Examples of semiconductor compounds are: as described herein, II-VI semiconductor compounds; III-V semiconductor compounds; III-VI semiconductor compounds; I-III-VI semiconductor compounds; IV-VI semiconductor compounds; or any combination thereof. For example, the semiconductor compound may include CdS, CdSe, CdTe, ZnS, ZnSe, ZnTe, ZnSeS, ZnTeS, GaAs, GaP, GaSb, HgS, HgSe, HgTe, InAs, InP, InGaP, InSb, AlAs, AlP, AlSb, or any combination thereof.

[0463] The full width at half maximum (FWHM) of the emission wavelength spectrum of the quantum dot can be about 45nm or less, such as about 40nm or less, or for example about 30nm or less. When the FWHM of the quantum dot is within these ranges, the quantum dot can have improved color purity or improved color reproducibility. In some embodiments, because the light emitted by the quantum dot is emitted in all directions, the wide viewing angle can be improved.

[0464] In some embodiments, quantum dots can be in the form of spherical, pyramidal, multi-armed, or cubic nanoparticles, nanotubes, nanowires, nanofibers, or nanoplates.

[0465] Because the band gap can be adjusted by controlling the size of the quantum dots, light with one or more suitable wavelength bands can be obtained from the quantum dot emission layer. Therefore, by using quantum dots of different sizes, a light-emitting device that emits light of one or more suitable wavelengths can be realized. In detail, the size of the quantum dots can be selected to emit red light, green light and / or blue light. In some embodiments, the size of the quantum dots can be configured to emit white light through a combination of one or more suitable colors of light.

[0467] The optically active layer 135 may be used to absorb incident light to generate excitons. Excitons may generate holes and electrons.

In some embodiments, the third compound included in the optically active layer 135 may act as an acceptor for receiving electrons, and may be referred to as an n-type or kind of compound.

[0678] It is confirmed from Tables 1 and 2 that, according to one or more embodiments, an optoelectronic device including all of the first compound, the second compound, and the third compound concurrently (e.g., simultaneously) has an EQE for green light sufficient for fingerprint sensing and an EQE for red light sufficient for blood pressure sensing.

[0679] According to one or more embodiments, by using the first to third compounds each having a relatively low deposition temperature, processability can be ensured, and thus, an optoelectronic device can be manufactured more easily. When the optoelectronic device included in the portable electronic device includes each (e.g., all) of the first to third compounds, the optoelectronic device can have excellent or suitable EQE for both (e.g., simultaneously) green light and red light. Therefore, a user of the electronic device can easily and accurately identify information such as a personal fingerprint and blood pressure through an electronic device with excellent or suitable portability.

[0680] It should be understood that the embodiments described herein should be considered in a descriptive sense only and not for the purpose of limitation. The description of features or aspects within each embodiment should generally be considered to be applicable to other similar features or aspects in other embodiments. Although one or more embodiments have been described with reference to the accompanying drawings, it will be understood by those of ordinary skill in the art that one or more suitable changes in form and details may be made therein without departing from the spirit and scope defined by the appended claims and their equivalents.
