Abstract:

The samples of rare earth Tb3+doped nanometer TiO2 powder were prepared by means of hydrothermal process with Nbutyl titanate \[Ti(OBu)4\] as the precursor and were studied by using PLE spectra and PL spectra. The results show that the Tb3+doped TiO2 powder can produce the characteristic peaks of Tb3+ at room temperature, and the luminescence intensity is related to the conditions of preparation. When the reaction temperature is 125℃, reaction time is 72 h and the molar concentration of doped Tb3+ is 12%, the PL spectra intensity of Tb3+ doped TiO2 powder arrives at the maximum.

Key words: hydrothermal, titanium dioxide, Tb3+, PL spectra
