Abstract

Photoluminescence (PL) and radiation-induced luminescence properties of Sn-doped zinc phosphate (SZP) glasses prepared with different cooling rates are investigated and associated with their glass structures. Although the shape of the PL spectrum is independent of the cooling rate, the emission intensity effectively changes with the cooling rate. The radial distribution functions of Sn in the SZP glasses prepared with different cooling rates coincide with each other. Electron spin resonance (ESR) measurement supports the fact that the trap density of slowly cooled glasses is higher than that of rapidly cooled glasses, and this fact is also suggested by the radiation-induced luminescence properties. Therefore, it is expected that these traps will work as storage sites associated with the radiation-induced luminescence.
