Optical Properties of Gel Titanium Dioxide Film, Modified By Metal Nanoparticles


The physic-chemical and optical properties of composite titanium dioxide films with gold, cobalt, copper, nickel and iron nanoparticles made using gel technology were studied in the work. The of titanium dioxide films structure synthesized according to different technologies is compared. The differential scanning calorimetry method was used to determine the temperatures of phase transitions of manufactured samples of various modifications of titanium dioxide. The transmission spectra of samples modified by metal nanoparticles with different concentrations were studied.

Keywords: sol-gel, gel method, titanium dioxide, modification, nanoparticles, gold, cobalt, copper, iron, nickel, spectroscopy.
