Abstract
Yb 0.1-100% doped Lu2O3 transparent ceramic scintillators were prepared by Konoshima Chemical. They had 60-80% transparency at wavelength longer than 240Â nm and absorption bands around 970Â nm due to 4f-4f transition of Yb3+ were observed. In photoluminescence and X-ray induced radioluminescence, Yb3+ charge transfer luminescence appeared at 330 and 490Â nm. Photoluminescence and scintillation decay times of the charge transfer luminescence resulted 0.5-1.5Â ns. 137Cs excited pulse height spectrum was evaluated to determine the light yield of the fast component and Yb 0.3% doped sample exhibited the highest light yield of â¼500Â ph/MeV.
