The Temperature Dependence of Scintillation Parameters in PbWO4 Crystals

Low temperature structural variations and molar heat capacity of stolzite, PbWO4

“…PbWO 4 is a fast and dense scintillator with good radiation resistance, however, its light yield is low [1] and varies drastically with temperature above 170 K due to thermal quenching of luminescence [5,6]. Thus, in order to improve the performance of electromagnetic calorimeters, a temperature stability better than 0.1 K at 291 K [1] or a cooling down of the calorimeter's environment to around 248 K [3] is necessary.…”

The Model for Luminescence Center Excitation in PbWO4

“…The pulse of luminescence was observed as a response on irradiation by electron beam pulse. Shape of blue luminescence pulse at 80 K was studied in [5]. The delayed (related to irradiation pulse end) rise front of luminescence pulse was observed.…”

“…The blue luminescence of PWO can be excited via two mechanisms [5]: (1) excitonic and (2) electron-hole (recombination). Two mechanisms of blue luminescence excitation were established from experiments in which PWO was irradiated by pulsed electron beam at low temperature (80 K): luminescence pulse rise front showed two components, a prompt and a delayed.…”

UV-VUV synchrotron radiation spectroscopy of NiWO4

“…The optical properties of different metal tungstates can be controlled by their composition and many wide band-gap tungstates are found to be promising materials for scintillator applications [3][4][5][6][7][8][9][10].…”
