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

摘要

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