Description

Technical Field

[0001] Disclosed are an organic compound, an optoelectronic device including the same, and an electronic device and an electronic equipment including the optoelectronic device. Background Art

[0002] An optoelectronic device is a device that converts light energy or an optical signal into electrical energy or an electrical signal. Examples of optoelectronic devices include a photovoltaic cell or a solar cell that converts light energy into electrical energy, and a photodetector or a photosensor that detects light energy and converts it into an electrical signal.

[0003] The optoelectronic device may include an organic compound that can be excited by light. The optoelectronic device may have a structure in which a first electrode is disposed over a substrate, and an intermediate layer and a second electrode are sequentially formed over the first electrode. In addition, the intermediate layer of the optoelectronic device is referred to as a photoactive layer, and may include an electron supply layer containing an electron donor and an electron acceptor layer containing an electron acceptor. As the electron donor, a p-type semiconductor material (e.g., SubPC) may be used, and as the electron acceptor, an n-type semiconductor material (e.g., Fullerene) may be used.

[0004] When light irradiates the optoelectronic device, absorption of the light causes excitation of electrons and generation of holes, and the excited electrons and the newly generated holes may form a pair to form an exciton. The exciton moves to the interface of the intermediate layer, and is again separated into an electron and a hole according to the characteristics of the interface. The separated electron and hole move to the respective electrodes, thereby generating a current.

[0005] An electronic device including an optoelectronic device and a light-emitting device is being 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 incident on the optoelectronic device. The optoelectronic device may recognize contact between the object and the electronic device by detecting incident light energy and converting it into an electrical signal. The optoelectronic device may be used as a fingerprint recognition sensor or the like. Summary of the Invention

[0377] The wet chemical process involves mixing an organic solvent and a precursor substance to grow quantum dot particle crystals. During crystal growth, the organic solvent naturally acts as a dispersant, distributing itself across the surface of the quantum dot crystals.

[0385] Each element included in the multi-element compounds such as the binary compound, ternary compound, and quaternary compound may exist in the particles at a uniform concentration or a non-uniform concentration.

[0386] On the other hand, the quantum dots may have a single structure or a core-shell dual structure in which the concentrations of the respective elements included in the corresponding quantum dots are uniform. For example, the substance included in the core and the substance included in the shell may be different from each other.

[0387] The shell of the quantum dots may function as a protective layer for preventing chemical denaturation of the core to maintain semiconductor characteristics and / or as a charging layer for imparting electrophoretic characteristics to the quantum dots. The shell may be a single layer or a multi-layer. 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 as it approaches the center.

Within this range, color purity or color reproducibility can be improved. In addition, since the light emitted by such quantum dots is emitted omnidirectionally, a wide viewing angle can be improved.

[0390] In addition, the morphology of the quantum dots may specifically be spherical, pyramidal, multi-arm, or cubic nanoparticles, nanotubes, nanowires, nanofibers, nanoplatelet particles, or the like.

[0391] By adjusting the size of the quantum dots, the band gap can be adjusted, and thus light in various wavelength ranges can be obtained in the quantum dot light-emitting layer. Therefore, by using quantum dots of different sizes, a light-emitting device that emits light of various wavelengths can be realized. Specifically, the size of the quantum dots can be selected to emit red, green, and / or blue light. In addition, the sizes of the quantum dots can be configured such that light of various colors is combined to emit white light.
