Photostimulated Luminescence and Radiation Hardness Properties of CsBr:(Eu 2+ ,KOH)

Meng Jia, Zhao Lili, Lixin Song

Abstract

CsBr: (Eu 2+ , KOH) powders were prepared by solid-state reaction. The photo luminescence (PL) spectra, photostimulated luminescence (PSL) spectra, Raman spectra and PSL lifetime spectra were systematically investi- gated, and the influence of KOH-adding on photostimulated luminescence and radiation hardness properties were discussed. The results reveal that the probability of radiationless transition increase due to hydroxyl ion (OH - ), with
