Research Article: Luminescent Properties of Ti4+-Doped White-Light Glasses Sio2- Al2O3 -Na2O -B2O3-Bao

Huiwang Lian and Yang Li*

We investigated the photoluminescence properties and decay curves of SiO2 -AL2O3- Na2 O - BaO-B2 O3-x TiO2 glasses prepared via the conventional melt quenching method. A broad emission band 400-800 nm peaking at 500 nm was observed in emission spectrum, while a very broad excitation spectral region (from 250 nm to 430 nm) and two main absorption bands at 260 and 400 nm were found. The fluorescence lifetime was measured and all the decay curves were approximated by an exponential decay function. Electron transition occurring between surface defects, oxygen vacancies or self-trapped excitons, support the observed spectroscopic data.
