[0003] One or more embodiments of this disclosure relate to organic compounds, light-emitting devices including organic compounds, display devices including light-emitting devices, and electronic devices including display devices. Background Technology

[0004] Self-emitting devices (e.g., organic light-emitting devices) in light-emitting devices have wide viewing angles, high contrast, short response times, and excellent characteristics in terms of brightness, driving voltage, and response speed.

[0005] A light-emitting device may include a first electrode, a hole transport region, an emitter layer, an electron transport region, and a second electrode, provided sequentially. Holes injected from the first electrode can move toward the emitter layer through the hole transport region. Electrons injected from the second electrode can move toward the emitter layer through the electron transport region. Charge carriers such as holes and electrons can recombine in the emitter layer to generate excitons. When the excitons descend from the excited state (e.g., through a transition or relaxation) to the ground state, light can be generated. Summary of the Invention

[0346] The emitter layer 130 may include quantum dots.

[0347] As used herein, the term "quantum dot" refers to a crystal of a semiconductor compound. Quantum dots can emit light at various suitable wavelengths depending on the size of the crystal. Furthermore, quantum dots can emit light at various suitable wavelengths by adjusting the proportions of the elements that make them up.

[0348] The diameter of quantum dots can be, for example, in the range of about 1 nm to about 10 nm.

[0349] Quantum dots can be synthesized by wet chemical processes, metal-organic chemical vapor deposition processes, molecular beam epitaxy processes and / or any suitable processes similar to them.

[0350] Wet chemistry processes involve mixing precursor materials with organic solvents and then growing quantum dot crystals. During crystal growth, the organic solvent naturally acts as a dispersant coordinated to the surface of the quantum dot crystals and controls the crystal growth, allowing the growth of quantum dot particles to be controlled through a less expensive and easier process compared to vapor deposition methods such as metal-organic chemical vapor deposition (MOCVD) or molecular beam epitaxy (MBE).

[0351] Quantum dots can 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 combinations thereof.

[0360] The shell of the quantum dots may act as a protective layer to prevent or reduce 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, where the concentration of the element present in the shell decreases along the direction toward the center of the core.

[0361] Examples of the shell of the quantum dots are oxides of metals, metalloids, and / or non-metals, semiconductor compounds, and combinations thereof. Examples of oxides of metals and / or non-metals are: binary compounds such as SiO2, Al2O3, TiO2, ZnO, MnO, Mn2O3, Mn3O4, CuO, FeO, Fe2O3, Fe3O4, CoO, Co3O4, and / or NiO; ternary compounds such as MgAl2O4, CoFe2O4, NiFe2O4, and / or CoMn2O4; and any suitable combination thereof.

[0362] The full width at half maximum (FWHM) of the emission wavelength spectrum of 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 and / or color reproducibility can be increased. In embodiments, because light emitted through quantum dots is emitted in all (e.g., substantially all) directions, a wide viewing angle can be improved.

[0363] In the embodiments, quantum dots may be in the form of spherical nanoparticles, cone-shaped nanoparticles, multi-armed nanoparticles, cubic nanoparticles, nanotubes, nanowires, nanofibers and / or nanoplates.

[0364] By adjusting the size of the quantum dots, the band gap can be adjusted, and thus, light of various suitable wavelengths can be obtained in the quantum dot emitting layer. Therefore, by using the quantum dots described above (either by using quantum dots of different sizes or by appropriately changing the proportions of elements in the quantum dot compound), a light-emitting device emitting light of various suitable wavelengths can be realized. In one or more embodiments, the size of the quantum dots or the proportions of elements in the quantum dot compound can be selected, thereby enabling the emission of red, green, and / or blue light. In one or more embodiments, the quantum dots can be configured to emit white light through a combination of various suitable colors of light.

In evaluating the maximum quantum efficiency, luminance / current density was measured using a luminance meter calibrated for wavelength sensitivity, and the maximum quantum efficiency was converted by assuming an angular luminance distribution (Lambertian) introduced by a completely reflective diffuser. The evaluation results of the light-emitting device characteristics are shown in Table 1 below.
