Abstract

We have investigated scintillation properties of the Pr-doped Li2O-GeO2 glasses. From the transmittance spectra, absorption bands due to 4f-4f transition of Pr3+ ions were observed. The samples showed the X-ray induced radioluminescence peaks originating from the 4f-4f transitions of the Pr3+ ion. The scintillation decay times were from 2.07 to 3.12 μs which are acceptable values for the scintillator. The Pr-doped Li2O-GeO2 glasses can be regarded as the candidate for the scintillation materials.
