Abstract

Correlation between excitation light source and the emission property of Sn²⁺-Ce³⁺ co-doped zinc phosphate glasses is examined. Although photoluminescence (PL) peaks of both Sn²⁺ and Ce ³⁺ shifted with increasing amount of Ce³⁺, there was little energy resonance between Sn²⁺ and Ce³⁺ emission centers. On the other hand, radioluminescence (RL) spectra excited by X-ray was independent of the Ce concentration, indicating that emission was mainly observed from Sn²⁺ emission center. It is expected that energy relaxation process in a RL preferentially occurs in an ns²-type emission center that possesses high transition probability of the excited state in the higher energy region.
