Electron and hole trapping in Ce3+- and Pr3+-doped lutetium pyrosilicate scintillator crystals studied by electron paramagnetic resonance

Original language description

Electron and hole trapping was studied in the Ce3+ and Pr3+ doped Lu2Si2O7 scintillation single crystals (LPS:Ce and LPS:Pr) by Electron Paramagnetic Resonance (EPR). Detailed EPR measurements of the X-ray irradiated LPS crystals revealed that holes generated by irradiation are predominantly trapped at oxygen lattice ions creating O- centers. The same X-ray irradiation creates also electron type centers which were attributed to Lu2+ ions, where the trapped electron at the Lu lattice ion is stabilized by a nearby defect, such as the oxygen vacancy and Ir3+ impurity ion. An origin of charge traps in this pyrosilicate structure and their role in scintillation mechanism is compared with the results previously described in literature on orthosilicates.
