Photoluminescence (PL) spectroscopy was used to study the charge carrier recombination processes in the C-doped and H-co-doped TiO2 thin films produced by magnetron sputtering. The radiative recombinations evident from the PL emission spectra (at about 470nm, 600nm and 850nm) were associated primarily with defects intrinsic to most thin films. Doping with C was found to promote the non-radiative recombination...
Anatase phase titanium dioxide thin films have been deposited at various substrate temperatures by chemical spray pyrolysis of an aerosol of titanyl acetylacetonate. Deposited TiO 2 films were nanocrystalline and preferentially oriented along [101] direction, uniform and adherent to the glass substrate. Best films processed at 450°C were characterized to analyze its phase composition, texture,...
