METHOD FOR DISPERSING SEMICONDUCTOR ULTRAMICROPARTICLE AND METHOD FOR PRODUCING SEMICONDUCTOR ULTRAMICROPARTICLE DISPERSION

摘要

PROBLEM TO BE SOLVED: To provide a method for uniformly dispersing high-luminous-efficiency semiconductor ultramicroparticles in a solvent containing water without detriment to their properties and to provide a method for producing a semiconductor ultramicroparticle dispersion by dispersing high-luminous-efficiency semiconductor ultramicroparticles in a solvent containing water without detriment to their properties.;SOLUTION: The method for dispersing the semiconductor ultramicroparticles is a method for dispersing the semiconductor ultramicroparticles in an aqueous solution containing the semiconductor ultramicroparticles and comprises alkalifying a mixed solution containing a solvent containing water, semiconductor ultramicroparticles, and a 3C or lower thioalchol by adjusting its pH with a pH modifier.;COPYRIGHT: (C)2005,JPO&NCIPI
