摘要：
We have investigated the photoluminescence (PL), scintillation, and photostimulated-luminescence (PSL) properties of Yb-doped SrCl2 transparent ceramics. The samples were prepared using the spark plasma sintering method. Emission peaks in the PL, scintillation, and PSL spectra were observed at 380 and 405 nm due to the spin-allowed and spin-forbidden 4f135d1-4f14 transitions of Yb2+, respectively. The PL quantum yield (QY) value elevated with increasing Yb concentration at 0.05%-1.0%, and the 1.0% Yb-doped SrCl2 transparent ceramic indicated the highest QY value. This concentration dependence was similar for the scintillation and PSL intensities.
