Abstract: | A systematic study of photoluminescence transitions of samarium ion (Sm3+) incorporated in titanium dioxide (TiO2) powder with anatase structure has been performed. Perceptible changes of luminescence under direct excitation as compared with indirect excitation of Sm3+ in titanium dioxide (TiO2:Sm3+) have been detected. Measurements of photoluminescence excitation spectra for all detected radiative transition of Sm3+ were accomplished. The values of asymmetry ratio were calculated for different excitation wavelengths. The dependence of luminescent intensity on Sm3+ doping concentration in TiO2 host was studied under direct and indirect excitation. Thus, evidences of the existence of the several Sm3+ sites in anatase TiO2 have been presented in this work |
