TiO 2 thin films doped with different concentration of Tb have been prepared and study of terbium photoluminescence in TiO 2 host has been presented. Thin films were deposited on silicon and SiO 2 substrates by magnetron sputtering of Ti–Tb mosaic target in oxygen atmosphere. XRD examinations show nanocrystalline nature of prepared thin films with TiO 2 -anatase and...
Rhodamine 6G (Rh6G)-doped amorphous titanium thin films were prepared by the sol–gel technique. The films were grown at room temperature (RT) and supported on silica-glass substrates, which were previously chemically activated. Photoluminescence (PL) spectra were registered at RT by using as photo excitation the 325nm He–Cd line. The PL versus the photon energy emission curves peak at around 3.2eV,...
