Effect of Tm doping on photoluminescence, scintillation, and thermally stimulated luminescence properties of MgAl2O4 single crystals

Scintillation and photostimulated-luminescence properties of Yb-doped SrCl2 transparent ceramics

“…In this case, recombination efficiency would be more dominant than energy transfer efficiency. 36,37) In Yb-doped SrCl 2 transparent ceramics, the scintillation and PSL results corresponded to the QY values, suggesting a big contribution to recombination efficiency.…”

Dosimetric properties of Tm2O3-doped Ca2BO3Cl

“…Luminescence peaks originated from the 4f→4f transition of Tm 3+ were detected. 21,30,32) The results indicates that the Tm 2 O 3 -doped Ca 2 BO 3 Cl showed TSL by recombination of holes and electrons at a Tm 3+ ion. Luminescence peaks due to a defect in a Ca 2 BO 3 Cl were not observed in the TSL spectra.…”

“…2 and previous studies, indicating that a final luminescence process for OSL was the 4f→4f transition of Tm 3+ . 21,30,32) The highest OSL intensity was observed from the 0.5% Tm 2 O 3 -doped Ca 2 BO 3 Cl, and OSL peaks derived from a defect in a Ca 2 BO 3 Cl were not detected in the OSL spectra. The results were consistent with the TSL ones.…”

“…2, the 0.5% Tm 2 O 3 -doped Ca 2 BO 3 Cl showed the highest scintillation intensity. 21,30) Further, a weak broad peak centered at 400 nm was detected. It could be related to unknown defects in a Ca 2 BO 3 Cl host.…”
