Luminescence and scintillation characterization of PbMoO4 crystal for neutrinoless double beta decay search

A PbMoO4 single crystal with optically good quality and crack free, bulk crystal is grown by the low thermal gradient Czochralski method. The luminescence and scintillation properties of the grown crystal are measured under the excitations by 4.4 eV UV, 662 keV γ, 5.5 MeV α, and β in the temperature range of 10–300 K. The light yield under UV and β excitations are found to enhance down to 10 K, however quenched below 50 K under γ and α...
