- Abstract
- By means of layered chemisorption of ions from solutions of electrolytes there have been obtained nanoparticles of copper sulfide in volume of a polymeric matrix. There have been conducted the x-ray analysis and measured optical spectra of the obtained samples. It has been found that the band gap for optical direct transitions depends on the sizes of particles. It is explained by optical quantum-dimensional effects in nanoparticles of copper sulfide. It has been established that in contrast to CdS nanoparticles, under thermal annealing of the system Cu2S : polymer matrix the band gap of copper sulfide increases that is connected with disintegration of nanoparticles.
