COPPER INDIUM SELENIDE NANOPARTICLES AND PREPARING METHOD OF THE SAME

摘要

PURPOSE: Copper indium selenide nano-particles and a method for preparing the same are provided to adjust the sizes and/or the compositions of nano-particles and to mass-produce copper indium selenide nano-particles of uniform sizes. CONSTITUTION: A method for preparing copper indium selenide nano-particles includes the following: a selenium metal is mixed with a first coordinate solvent to be reacted to prepare a selenium precursor solution; a copper precursor and an indium precursor are mixed with a second coordinate solvent to prepare a copper/indium precursor solution; and the selenium precursor solution and the copper/indium precursor solution are mixed and heated to form copper indium selenide nano-particles. The selenium precursor solution preparing process further includes a carbon monoxide introducing process.
