Systematic Investigation of Defect-Mediated Photoluminescence Through Radiation-Induced Displacement Damage

摘要

1. Photoluminescence emission and lifetime can be used to detect proton-induced damage in YBO_3:Ce~(3+). 1.1 No shifts, no relative peak changes - only observed overall decrease of emission intensity 1.2 Only able to get effects at high fluences. 2. The damage-induced lifetime is concentration-dependent. 2.1 Allows us to develop design parameters for which phosphor concentrations are optimal for detecting damage.
