[0003] One or more embodiments of the present disclosure relate to organometallic compounds, organic light-emitting devices including the organometallic compounds, and electronic devices and consumer products including the organic light-emitting devices. Background Art

[0004] The organic light emitting device is a self-emitting device that has a wide viewing angle, a high contrast ratio, a short response time, and excellent characteristics in terms of brightness, driving voltage, and response speed compared to devices in the related art, and produces a full-color image.

[0005] In an example, the 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 by the first electrode move toward the emission layer through the hole transport region, and electrons provided by 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.

[0187] In one or more embodiments, the emission layer of the organic light-emitting device may include a dopant and a host, and the dopant may include an organic metal compound represented by Formula 1. That is, the organic metal compound may act as a dopant. The emission layer may emit, for example, blue light.

[0190] In embodiments, the subject matter can be understood by reference to the description of the subject matter provided herein.

[0191] Therefore, a light-emitting device (eg, an organic light-emitting device) including the organometallic compound represented by Formula 1 may have high color purity, high light emission efficiency, low driving voltage, and long lifespan characteristics.

[0192] In an embodiment, the organic metal compound represented by Formula 1 may emit blue light.

[0484] quantum dots

[0485] The emissive layer may comprise quantum dots.

[0486] The term "quantum dot" as used herein refers to a crystal of a semiconductor compound, and may include any suitable material capable of emitting light of various suitable emission wavelengths depending on the size of the crystal.

[0487] The diameter of the quantum dot can be, for example, about 1 nm to about 10 nm.

[0488] The quantum dots may be synthesized by a wet chemical process, a metal organic chemical vapor deposition process, a molecular beam epitaxy process, and / or any process similar thereto.

[0489] 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, so that the growth of the quantum dot particles can be controlled by 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).

[0490] 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.

[0491] Examples of II-VI semiconductor compounds are: binary compounds such as CdS, CdSe, CdTe, ZnS, ZnSe, ZnTe, ZnO, HgS, HgSe, HgTe, MgSe, MgS, etc.; ternary compounds such as CdSeS, CdSeTe, CdSTe, ZnSeS, ZnSeTe, ZnSTe, HgSeS, HgSeTe, HgSTe, CdZnS, CdZn Se, CdZnTe, CdHgS, CdHgSe, CdHgTe, HgZnS, HgZnSe, HgZnTe, MgZnSe, MgZnS, etc.; quaternary compounds, such as CdZnSeS, CdZnSeTe, CdZnSTe, CdHgSeS, CdHgSeTe, CdHgSTe, HgZnSeS, HgZnSeTe, HgZnSTe, etc.; or any combination thereof.

[0496] Examples of Group IV elements or compounds are: single elements, such as Si, Ge, etc.; binary compounds, such as SiC, SiGe, etc.; or any combination thereof.

[0497] Each element contained in the multi-element compound (eg, binary compound, ternary compound, and quaternary compound) may be present in the particle at a uniform concentration or a non-uniform concentration.

[0498] 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 may have a core-shell dual structure. For example, the material contained in the core and the material contained in the shell may be different from each other.

[0499] The shell of a quantum dot can act as a protective layer to prevent or reduce chemical denaturation of the core to maintain semiconductor properties and / or 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, wherein the concentration of the element present in the shell decreases along the direction toward the center of the core.

[0500] Examples of quantum dot shells are oxides of metals, metalloids and / or non-metals, semiconductor compounds or combinations thereof. Examples of oxides of metals, metalloids and / or non-metals 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 , Fe3 O 4 , CoO, Co 3 O 4 , NiO, etc.; ternary compounds, such as MgAl 2 O 4 、CoFe 2 O 4 、NiFe 2 O 4 、CoMn 2 O 4 etc.; or any combination thereof.

[0501] The full width at half maximum (FWHM) of the emission wavelength spectrum of the quantum dots can be about 45 nm or less, such as about 40 nm or less, such as about 30 nm or less, and within these ranges, the color purity and / or color reproducibility of the quantum dots can be improved. In addition, since the light emitted by the quantum dots is emitted in all (e.g., substantially all) directions, the wide viewing angle can be improved.

[0502] Furthermore, quantum dots may be in the form of spherical nanoparticles, pyramidal nanoparticles, multi-armed nanoparticles, cubic nanoparticles, nanotubes, nanowires, nanofibers, nanoplates, and the like.

[0503] By controlling the size of the quantum dots, the energy band gap can be adjustable so that light with various suitable wavelength bands can be obtained from the emission layer containing the quantum dots. Therefore, by using quantum dots of different sizes, an organic light-emitting device that emits light of various suitable wavelengths can be realized. In an embodiment, the size of the quantum dots can be selected to emit red light, green light and / or blue light. In addition, the size of the quantum dots can be configured to emit white light by combining various suitable colors of light.
