Title:
SEMICONDUCTOR NANOPARTICLES AND PROCESS FOR PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2007/086279
Kind Code:
A1
Abstract:
A process for the production of semiconductor nanoparticles which realizes both uniform crystallite size and high crystallinity with the agglomeration thereof inhibited. This process is characterized by comprising the step (a) of generating nano-size particles from a semiconductor raw material and dispersing the particles in a gas phase, the step (b) of heat-treating the particles while keeping the particles in a state dispersed in the gas phase, and the step (c) of collecting the heat-treated particles immediately after the heat treatment with a solution of a surface modifier for modifying the surfaces of the particles.
