Preparation of Copper Selenide Nanoparticles

摘要

A process for producing copper selenide nanoparticles by effecting conversion of a nanoparticle precursor composition comprising copper and selenide ions to the material of the copper selenide nanoparticles in the presence of a selenol compound. Copper selenide-containing films and CIGS semiconductor films produced using copper selenide as a fluxing agent are also disclosed.
