We have investigated the photoluminescence (PL), scintillation and thermally-stimulated luminescence (TSL) dosimeter properties of Pr-doped 12CaO·7Al2O3 (Pr:C12A7) crystals prepared by the floating zone (FZ) method. In PL emission and excitation spectral measurements, some emission bands around 600–650 and 850–950 due to the 4f-4f transitions of Pr3+ were observed under excitation at 450–500nm. The...
