Abstract
In this study, we prepared the Eu-doped 10Al2O3-90SiO2 glasses with different Eu concentrations (0.1, 0.3, 1.0, and 3.0 %) and investigated the photoluminescence (PL) and scintillation properties. All samples showed the Eu2+ and Eu3+ luminescence peaks at around 450 and 600 nm, respectively. The quantum yield monitored Eu2+ luminescence decreased from 82.7 to 2.3 % with increasing Eu concentration. Scintillation peaks of Eu2+ and Eu3+ were observed at around 450 and 600 nm, the same as PL. We measured pulse height spectra to estimate light yields (LY). All samples indicated the full-energy absorption peaks, and especially the 0.3 % Eu-doped sample had the highest LY (1400 photons/5.5 MeV) among all samples. The energy resolution and α/γ ratio of the 0.3 % Eu-doped sample were 13 % and 0.3, respectively.
