[0001] Cross - Reference to Related Applications

[0002] This application claims the priority and benefit of Korean Patent Application No. 10-2024-0010149, filed with the Korean Intellectual Property Office on January 23, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] One or more aspects of embodiments of the present disclosure relate to optoelectronic devices and electronic devices including the optoelectronic devices. Background Art

[0004] Optoelectronic devices are devices that convert light energy into electrical energy and / or convert optical signals into electrical signals. Examples of optoelectronic devices are optical or solar cells that convert light energy into electrical energy, and / or optical detectors or sensors that detect and convert optical signals into electrical signals, etc.

[0005] Electronic devices including optoelectronic devices and light-emitting devices have been developed. Light emitted from the light-emitting device may be reflected from an object (e.g., a user's finger) in contact with the electronic device and then incident on the optoelectronic device. When the optoelectronic device detects the incident optical signal and converts the optical signal into an electrical signal, contact between the object and the electronic device can be recognized. Thus, the optoelectronic device can be used as, for example, a fingerprint recognition sensor. Summary of the Invention

[0043] Reference will now be made in more detail to one or more embodiments, examples of which are illustrated in the accompanying drawings, wherein like reference numerals always refer to like elements and their repeated description may not be provided. In this regard, the present embodiments may have different forms and should not be construed as limited to the description set forth herein. Accordingly, one or more embodiments are described in more detail only by reference to the accompanying drawings to illustrate aspects of this specification. If reference is made to one or more embodiments described with reference to the accompanying drawings, aspects and features of the present disclosure and methods of implementing the same will be apparent. Identical or corresponding components will be denoted by the same reference numerals and thus their redundant description will not be provided.

[0044] As used herein, the term "and / or" includes any combination and all combinations of one or more of the associated listed items. Expressions such as "at least one of...", "one of...", "selected from...", and "selected from among..." when preceding or following a list of elements modify the entire list of elements, rather than individual elements of the list. For example, throughout this disclosure, the expression "at least one of a, b, and c" indicates only a, only b, only c, both a and b (e.g., a and b simultaneously), both a and c (e.g., a and c simultaneously), both b and c (e.g., b and c simultaneously), all of a, b, and c, or variations thereof.

[0045] Unless otherwise defined, all chemical names, technical and scientific terms, and terms defined in common dictionaries shall be interpreted to have a meaning consistent with the context of the relevant field and shall not be interpreted in an ideal or overly formal sense. It will be understood that although the terms "first" and / or "second" etc. may be used herein to describe one or more suitable components, these components shall not be limited by these terms. These terms are only used to distinguish one component from another. Thus, without departing from the teachings of this disclosure, a first element may be referred to as a second element. Similarly, a second element may be referred to as a first element. Expressions used in the singular form such as "a", "one", and "the" are intended to also cover the plural forms, unless they have an apparently different meaning in the context.

[0046] It will be further understood that the terms "comprises", "comprising", and / or "comprise" as used herein specify the presence of stated features or elements, but do not preclude the presence or addition of one or more other features or elements.

[0047] As used herein, the term "use" may be considered to be synonymous with the term "utilize" respectively.

[0048] The term "may" will be understood to refer to "one or more embodiments of this 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 this disclosure", each of which includes the corresponding listed item.

[0049] In the following embodiments, if one or more components such as a layer, a film, a region, and / or a plate are referred to as being "connected to" another component or "on" another component, this can include not only the case where the other component is "immediately on" the layer, the film, the region, and / or the plate, but also the case where other components can be located therebetween. For ease of illustration, the dimensions of the elements in the drawings may be exaggerated. In other words, since the dimensions and thicknesses of the components in the drawings are arbitrarily shown for ease of illustration, the following embodiments are not limited thereto.

[0050] For ease of description, spatially relative terms such as "under", "below", "lower", "above", "upper", "bottom", and "top" may be used herein to describe the relationship of one element or feature to another element or feature as shown in the drawings. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is flipped, an element described as "under" or "below" another element or feature will then be oriented "above" or "over" the other element or feature. Thus, the term "under" can encompass both an upper and a lower orientation. The device may be otherwise oriented (rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein are to be interpreted accordingly.

[0051] In context, "consisting essentially of" indicates that any additional components will not substantially affect the chemical, physical, optical, or electrical properties of the semiconductor film.

[0052] In addition, in this specification, the phrase "in a plane" or "plan view" indicates observing the target portion from the top, and the phrase "in a cross section" indicates observing the cross section formed by vertically cutting the target portion from the side.

[0053] Those of ordinary skill in the art will recognize that, given the overall content of this disclosure, each suitable feature of the various embodiments of this disclosure can be partially or wholly combined or merged with each other, and can be interconnected and operated in various suitable ways, and unless otherwise stated or implied, each embodiment can be implemented independently of each other or in combination with each other in any suitable way.

[0369] In the specification, the thermally activated delayed fluorescence material can be selected from compounds capable of emitting thermally activated delayed fluorescence based on a thermally activated delayed fluorescence emission mechanism.

[0370] The thermally activated delayed fluorescence material included in the emission layer 130 can act as a host or a dopant depending on the type or kind of other materials included in the emission layer 130.

[0371] According to one or more embodiments, the difference between the triplet energy level and the singlet energy level of the thermally activated delayed fluorescence material can be greater than or equal to about 0 eV and less than or equal to about 0.5 eV. When the difference between the triplet energy level (eV) and the singlet energy level (eV) of the thermally activated delayed fluorescence material satisfies the range described herein, up-conversion from the triplet state to the singlet state of the thermally activated delayed fluorescence material can occur effectively, and thus, the luminous efficiency of the light-emitting device 10 can be improved.

[0377] The emission layer 130 may include quantum dots.

[0378] As used herein, the term "quantum dots" refers to crystals of semiconductor compounds and may include any material capable of emitting light of one or more suitable emission wavelengths according to the size of the crystals.

[0379] The diameter of the quantum dots may be, for example, in the range of about 1 nm to about 10 nm.

[0380] Quantum dots can be synthesized by a wet chemical process, a metalorganic chemical vapor deposition process, a molecular beam epitaxy process, or any process similar thereto.

[0381] The wet chemical process is a method including mixing precursor materials with an organic solvent and then growing quantum dot particle crystals. When the crystals grow, the organic solvent naturally acts as a dispersant coordinated on the surface of the quantum dot crystals and controls the growth of the crystals, so that the growth of the quantum dot particles can be controlled or selected by a process that is lower in cost and easier than vapor deposition methods such as metalorganic chemical vapor deposition (MOCVD) or molecular beam epitaxy (MBE).

[0382] Quantum dots may include II-VI group semiconductor compounds, III-V group semiconductor compounds, III-VI group semiconductor compounds, I-III-VI group semiconductor compounds, IV-VI group semiconductor compounds, group IV elements or compounds, or any combination thereof.

[0383] Examples of II-VI semiconductor compounds are: binary compounds such as CdS, CdSe, CdTe, ZnS, ZnSe, ZnTe, ZnO, HgS, HgSe, HgTe, MgSe or MgS; ternary compounds such as CdSeS, CdSeTe, CdSTe, ZnSeS, ZnSeTe, ZnSTe, HgSeS, HgSeTe, HgSTe, CdZnS, CdZnSe, CdZnTe, CdHgS, CdHgSe, CdHgTe, HgZnS, HgZnSe, HgZnTe, MgZnSe or MgZnS; quaternary compounds such as CdZnSeS, CdZnSeTe, CdZnSTe, CdHgSeS, CdHgSeTe, CdHgSTe, HgZnSeS, HgZnSeTe or HgZnSTe; or any combination thereof.

[0388] 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.

[0389] Each element included in a multi-element compound such as a binary compound, a ternary compound and a quaternary compound may be present in the particles at a substantially uniform concentration or a non-uniform concentration.

[0390] In one or more embodiments, the quantum dots may have a single structure in which the concentration of each element in the quantum dots is substantially uniform, or 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.

[0391] The shell of the quantum dots may 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 dots. The shell may be a single layer or multiple layers. The interface between the core and the shell may have a concentration gradient in which the concentration of the elements present in the shell decreases towards the center of the core.

[0392] Examples of materials for the shell of the quantum dots can be oxides of metals, metalloids or non-metals, semiconductor compounds, and any combination thereof. Examples of oxides of metals, metalloids or non-metals are: binary compounds such as SiO2, Al2O3, TiO2, ZnO, MnO, Mn2O3, Mn3O4, CuO, FeO, Fe2O3, Fe3O4, CoO, Co3O4 or NiO; ternary compounds such as MgAl2O4, CoFe2O4, NiFe2O4 or CoMn2O4; and any combination thereof.

[0393] The full width at half maximum (FWHM) of the emission wavelength spectrum of the quantum dots can be about 45 nm or less, for example about 40 nm or less, for example about 30 nm or less, and within these ranges, color purity or color reproducibility can be improved. In some embodiments, since the light emitted by the quantum dots is emitted in all directions, a wide viewing angle can be improved.

[0394] In some embodiments, the quantum dots can be in the form of spherical particles, pyramid-shaped particles, multi-arm particles, cubic nanoparticles, nanotubes, nanowires, nanofibers or nanoplates.

[0395] Since the band gap can be adjusted by controlling the size of the quantum dots, light having one or more suitable wavelength bands can be obtained from the quantum dot emitting layer. Thus, by using quantum dots of different sizes, a light emitting device that emits light of one or more suitable wavelengths can be realized. In one or more embodiments, the size of the quantum dots can be selected to emit red, green and / or blue light. In some embodiments, the size of the quantum dots can be configured to emit white light by a combination of one or more suitable colors of light.

[0399] The optically active layer 135 may generate excitons by absorbing light incident on the electronic device. The excitons may generate holes and electrons. For example, the optically active layer 135 may absorb light to generate an electrical signal. For example, the first compound included in the optically active layer 135 may serve as a donor for providing electrons, and the second compound included in the optically active layer 135 may serve as an acceptor for receiving electrons. Accordingly, the optoelectronic device 30 including the optically active layer 135 may be used as an optical sensor.
