Abstract
In this paper BaO-B2O3-SiO2 glass and glass-ceramics doped with cerium oxide are reported. The effect of SiO2 content on the efficiency of the thermoluminescence process was investigated. Our study revealed that up to 20 mol% SiO2 no phase separation appears due to the high content of Ba and Ce modifiers. The results confirm that the gradual introduction of SiO2 into the borate glass lowers the efficiency of the luminescence processes. However, it enhances the thermal stability and reduces ΔH of crystallization. As a result, we have obtained glass-ceramics which thermoluminescence (TL) efficiency is comparable with commercial crystalline materials. The optical properties of barium cerium borate glasses (BaCeB) were improved by simultaneously SiO2 addition and process of heat treatment. Finally, our glass-ceramics has promising potential as an active material for thermoluminescent detectors.
