摘要： There is provided a method of preparing formamidinium lead halide perovskite quantum dots having a photoluminescence quantum yield higher than before. The disclosed method comprises steps of: preparing a lead halide solution by dissolving lead halide (II), oleic acid and oleylamine in a nonpolar solvent; preparing a formamidinium solution by dissolving formamidine acetate salt and oleic acid in a nonpolar solvent; mixing the formamidinium solution and the lead halide solution to form quantum dots; and centrifuging the mixed solution to obtain sediment; dispersing the sediment in a nonpolar solvent to prepare a crude quantum dot solution; mixing the crude quantum dot solution with methyl acetate; and centrifuging the crude quantum dot solution mixed with the methyl acetate to obtain sediment as purified quantum dots. The durable quantum dots are stably formed by injecting the lead halide solution into the formamidinium solution heated at 60° C.-90° C.

摘要： Provided are: a light-emitting layer for a perovskite light-emitting device; a method for manufacturing the same; and a perovskite light-emitting device using the same. The method of the present invention for manufacturing a light-emitting layer for a halide perovskite light-emitting device comprises a step of forming a first nanoparticle thin film by coating, on a member for coating a light-emitting layer, a solution comprising halide perovskite nanoparticles including a perovskite nanocrystal structure. Thereby, a nanoparticle light emitter has therein a halide perovskite having a crystal structure in which FCC and BCC are combined; and can show high color purity. In addition, it is possible to improve the luminescence efficiency and luminance of a device by making perovskite as nanoparticles and then introducing the same into a light-emitting layer.

摘要： A finely divided metal-containing compound can be efficiently prepared by irradiating a mixed vapor phase of an organometallic compound in a concentration to exceed a specified lower limit and a reactant gaseous compound with laser beams having an incident energy density to exceed a specified lower limit. When the reactant gaseous compound in the vapor phase is an oxygen-containing compound, e.g., air, the resultant powdery product is an oxide of the metallic element of the organometallic compound. When the reactant gaseous compound in the vapor phase is a halogen-containing compound, e.g., methyl halides, the resultant powdery product is a halide of the metallic element of the organometallic compound. When the reactant gaseous compound is a second organometallic compound, of which the metallic element is not the same as the metallic element in the first organometallic compound, the resultant powdery product is a composite metallic powder of which the distribution of the two metallic elements is uniform throughout each particle. No particles of either one of the metallic elements alone are contained in the powder as evidenced by the EPMA analysis.

摘要： A process for separating inorganic substances involving their abstraction from a mixture with near-supercritical inorganic fluids. One or more inorganic substances are abstracted and then separatively recovered by retrograde condensations. The process particularly is applicable with mixtures obtained from the chlorination of metalliferous ores and may be conjoined to many ancillary metal abstraction processes such as volatilizations, distillations or electrolyses.
