METHOD FOR PRODUCTION OF CADMIUM TELLURIDE NANOPARTICLES WITH SPHALERITE STRUCTURE

摘要

FIELD: nanotechnologies.;SUBSTANCE: invention is related to technology of nanomaterials production, in particular to cadmium telluride nanoparticles, and may be used for development of optical instruments, detectors of ionising radiations, catalysts. Initial single crystals of cadmium telluride are decomposed in alkaline melt: sodium or potassium hydroxide in atmosphere of nitrogen till homogenisation of melt, which is then cooled down to 0°C, processing it by water with gradual addition of hydrochloric acid to obtain value pH of final solution equal to 2-3 at the temperature of not higher than 1-5°C and residue of cadmium telluride with nanoparticle size of around 2 nm with sphalerite structure, which is then filtered.;EFFECT: simplified technology, reduction of dimensions of produced nanoparticles down to 2 nm and their production in stable cubic phase (sphalerite).;2 ex
