Electron and hole trapping in Li2MoO4 cryogenic scintillator
Original language description
The origin and thermal stability of charge trapping centers were studied in Li2MoO4 cryogenic scintillators by correlated electron paramagnetic resonance (EPR) and thermally stimulated luminescence (TSL) measurements. Up to five electron and three hole trapping centers were detected in the crystals X-ray irradiated at 77 K. The electron traps were ascribed to MoO43− molecular complexes, unperturbed and perturbed by neighboring defects, while the hole traps – to O− lattice ions perturbed by lithium and molybdenum vacancies. The thermal stability of the trapping centers was studied and the depths of electron and hole traps were determined. The TSL peaks observed in the 77–300 K temperature range were related to the depletion of the detected paramagnetic centers. Influence of the revealed centers on the scintillation light yield is discussed.
