Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to and the benefit of Korean Patent Application No. 10-2023-0078353 filed in the Korean Intellectual Property Office on June 19, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to a light-emitting device including an amine compound, an electronic device and an electronic device each including the light-emitting device, and the amine compound. Background Art

[0004] Among light-emitting devices, organic light-emitting devices are self-emissive devices that have wide viewing angles, high contrast, short response times, and superior characteristics in terms of brightness, driving voltage, and response speed compared to devices in the related art.

[0005] As an example, an organic light-emitting device may have a structure in which a first electrode is arranged on a substrate, and a hole transport region, an emission layer, an electron transport region, and a second electrode are sequentially formed on the first electrode. Holes provided from the first electrode move toward the emission layer through the hole transport region, and electrons provided from the second electrode move toward the emission layer through the electron transport region. Carriers (such as holes and electrons) recombine in the emission layer to generate excitons. Excitons can transition from an excited state to a ground state, thereby generating light.

[0006] It is to be understood that this background technology section is intended, in part, to provide a useful background for understanding the technology. However, this background technology section may also include ideas, concepts, or cognitions that were not part of the known or understood by a person skilled in the relevant art before the corresponding effective filing date of the subject matter disclosed herein.

[0057] The present disclosure will now be described more fully below with reference to the attached drawings in which embodiments are shown. However, the present disclosure may be embodied in different forms and should not be construed as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure will be thorough and complete and will fully convey the scope of the present disclosure to those skilled in the art.

[0058] In the drawings, the size, ratio, and dimensions (eg, thickness) of elements may be exaggerated for ease of description and for clarity. Like reference numerals and reference characters refer to like elements throughout.

[0059] In the specification, it will be understood that when an element (or region, layer, portion, etc.) is referred to as being "on", "connected to" or "coupled to" another element (or region, layer, portion, etc.), it may be directly on, directly connected to or directly coupled to the other element (or region, layer, portion, etc.), or one or more intervening elements may be present therebetween. In a similar sense, when an element (or region, layer, portion, etc.) is described as "covering" another element (or region, layer, portion, etc.), it may directly cover the other element (or region, layer, portion, etc.), or one or more intervening elements may be present therebetween.

[0060] In the specification, when an element is "directly on," "directly connected to," or "directly coupled to" another element, there are no intervening elements. For example, "directly on" may mean that two layers or two elements are disposed without another element (such as an adhesive element) between them.

[0061] In the specification, expressions used in the singular such as “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0062] In the specification, the term "and / or" includes any and all combinations of one or more related listed items. For example, "A and / or B" can be understood to mean "A, B, or A and B". The terms "and" and "or" can be used in a connecting sense or a separating sense and can be understood to be equivalent to "and / or".

[0063] In the specification and claims, the term "at least one of" is intended to include the meaning of "at least one selected from the group consisting of" for the purposes of its meaning and interpretation. For example, "at least one of A, B, and C" may be understood to mean only A, only B, only C, or any combination of two or more of A, B, and C, such as ABC, ACC, BC, or CC. When following a list of elements, the term "at least one of" modifies the entire list of elements and does not modify the individual elements of the list.

[0064] It will be understood that although the terms first, second, etc. may be used to describe various elements in this article, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. Therefore, without departing from the teachings of the present disclosure, the first element may be referred to as the second element. Similarly, without departing from the scope of the present disclosure, the second element may be referred to as the first element.

[0065] For ease of description, spatially relative terms such as "below," "under," "down," "above," or "on" may be used herein to describe the relationship between one element or component and another element or component as illustrated in the accompanying 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 accompanying drawings. For example, in the case where the device illustrated in the accompanying drawings is turned over, a device that is "below" or "below" another device may be placed "above" the other device. Accordingly, the illustrative term "below" may include both a lower position and an upper position. The device may also be oriented in other directions, and therefore the spatially relative terms may be interpreted differently depending on the orientation.

[0066] As used herein, the term "about" or "approximately" includes the stated value and means within an acceptable range of deviation of the stated value determined by one of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of the stated quantity (i.e., the limitations of the measurement system). For example, "about" can mean within one or more standard deviations of the stated value, or within ±20%, ±10%, or ±5% of the stated value.

[0067] It should be understood that the terms “comprises,” “comprising,” “include,” “including,” “have,” “having,” “contains,” and “containing” and the like are intended to indicate the presence of the recited features, integers, steps, operations, elements, components, or combinations thereof in the present disclosure, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or combinations thereof.

[0068] Unless otherwise defined or implied herein, all terms (including technical terms and scientific terms) used have the same meaning as those commonly understood by those skilled in the art to which the present disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an ideal or overly formal sense unless clearly defined in the specification.

[0591] Examples of Group IV elements or compounds may include: single element materials such as Si and Ge, etc.; binary compounds such as SiC and SiGe, etc.; or any combination thereof.

For example, the above formula refers to the type of element included in the compound, wherein the ratio of the elements in the compound may vary. For example, AgInGaS 2 AgIn x Ga 1-x S 2 (where x is a real number between 0 and 1).

[0593] In an embodiment, the quantum dot may have a single structure in which the concentration of each element in the quantum dot is uniform, or the quantum dot may have a core-shell structure. In an embodiment, when the quantum dot has a core-shell structure, the material included in the core and the material included in the shell may be different from each other.

[0594] The shell of the quantum dot can be used as a protective layer to prevent chemical denaturation of the core to maintain semiconductor properties, and / or can be used as a charging layer to impart electrophoretic properties to the quantum dot. The shell can be a single layer or multiple layers. The interface between the core and the shell can have a concentration gradient, wherein the concentration of the material present in the shell decreases toward the center of the core.

[0595] Examples of the shell of the quantum dot may include metal oxides, metalloid oxides, non-metal oxides, semiconductor compounds, or any combination thereof. Examples of metal oxides, metalloid oxides, or non-metal oxides may include: 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 O4 , CoO, Co 3 O 4 and NiO, etc.; ternary compounds, such as MgAl 2 O 4 、CoFe 2 O 4 、NiFe 2 O 4 and CoMn 2 O 4 etc.; or any combination thereof.

[0596] Examples of semiconductor compounds may include: as described herein, 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; or any combination thereof.

[0597] The quantum dots may have a full width at half maximum (FWHM) of an emission wavelength spectrum in the range of about 45 nm to about 40 nm. For example, the quantum dots may have a FWHM of an emission wavelength spectrum equal to or less than 30 nm. When the FWHM of the emission wavelength spectrum of the quantum dots is within these ranges, the quantum dots may have improved color purity or improved color reproducibility. In addition, since the light emitted by the quantum dots is emitted in all directions, a wide viewing angle may be improved.

[0598] In embodiments, the quantum dots may be in the form of spherical nanoparticles, pyramidal nanoparticles, multi-armed nanoparticles, cubic nanoparticles, nanotubes, nanowires, nanofibers, or nanoplates.

[0599] Because the energy band gap can be adjusted by controlling the size of the quantum dots, light with various wavelength bands can be obtained from the quantum dot emission layer. Accordingly, by using quantum dots of different sizes, a light-emitting device that emits light of various wavelength bands can be implemented. For example, the size of the quantum dots or the ratio of elements in the quantum dot compound can be selected to emit red light, green light, and / or blue light. In an embodiment, the size of the quantum dots can be configured to emit white light through a combination of various colors of light.
