SYNTHESIS AND INVESTIGATION OF THIN TiO₂ FILMS, DOPED WITH COPPER NANOPARTICLES

Вестник Северо-Кавказского федерального университета, 2022
Thin films of titanium dioxide, doped with copper nanoparticles, were synthesized by the method of deposition on the rotating substrate. The obtained films were dried at room temperature and at temperature of TiO2 calcination and studied by ellipsometry,
