[0168] Manufacturing example 1: Synthesis of InP / ZnS core-shell quantum dot particles

[0169] Fabrication of InP nuclear quantum dots

[0170] Add 0.4mmol (0.058g) of indium acetate (Indium acetate), 0.6mmol (0.15g) of palmitic acid (0.15g), and 20mL of 1-octadecene into the reactor, and heat to 120°C under vacuum. After 1 hour, the atmosphere in the reactor was switched to nitrogen. After heating to 280°C, quickly inject a mixed solution of 0.2mmol (58uL) of tris(trimethylsilyl)phosphine (TMS3P) and 1.0mL of trioctylphosphine, and react for 20 minutes. Acetone was added to the reaction solution rapidly cooled to normal temperature, and the precipitate obtained by centrifugation was dispersed in toluene. The obtained InP semiconductor nanocrystal shows the UV first absorption maximum wavelength of 560-590nm.

Abstract

According to the present invention, a quantum dot dispersion comprises: a quantum dot; and a first solvent having a dielectric constant less than 12.0 at 20 DEG C, but does not comprise a halogenatedhydrocarbon-based solvent, an aromatic hydrocarbon-based solvent, and an aliphatic saturated hydrocarbon-based solvent.

Description

technical field [0001] The present invention relates to a quantum dot dispersion containing a solvent having a specific dielectric constant value, a self-luminous photosensitive resin composition containing the quantum dot dispersion, a color filter and an image manufactured using the self-luminous photosensitive resin composition display device. Background technique [0002] A color filter is a thin-film optical component that extracts three colors of red, green, and blue from white light to form fine pixel units, and the size of one pixel is on the order of tens to hundreds of microns. Such a color filter adopts a structure in which a black matrix layer and a pixel portion are sequentially laminated, wherein the black matrix layer is formed in a predetermined pattern on a transparent substrate to shield the boundary portion between individual pixels, and the pixel portion The section arranges three primary colors of a plurality of colors (usually red R, green G, and blue ...
