SYNTHESIS AND INVESTIGATION OF THIN TiO<sub>2</sub> FILMS, DOPED WITH COPPER NANOPARTICLES
Abstract
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, spectrophotometry and infrared spectroscopy. The concentration of copper sol in the solution for producing films affects the thickness of the resulting coating films and their refractive index. Adding copper nanoparticles in the titanium dioxide films leads to the appearance of absorption bands at 650 - 750 nm.
