Luminescence and charge trapping features of archPbMoO4 lead molybdate crystals grown from archaeological lead

Popis výsledku v původním jazyce

A PbMoO4 single crystal as a perspective detector for neutrinoless double beta decay experiment was grown by the Czochralski technique from high purity raw materials including archaeological lead. Charge trapping and energy transfer phenomena in this crystal have been studied by electron paramagnetic resonance (EPR) and wavelength-resolved thermally stimulated luminescence (TSL). EPR revealed several impurities, which however do not participate in the charge trapping processes. Self-trapped electron and (MoO4)3--VPb centers creation under laser light was confirmed. The TSL peak at 41 K was ascribed to the de-trapping of self-trapped electrons. The 53 K TSL peak, in particular, is created by re-trapping processes. The trap depths and frequency factors for the 90 K and 105 K TSL glow peaks were determined. The peaks have been referred to the (MoO4)3--VPb decay.
