Luminescence of CaWO4, CaMoO4, and ZnWO4 scintillating crystals under different excitations

Abstract:

The luminescence spectra of CaW O4, CaMo O4, and ZnW O4 scintillating crystals were investigated in the temperature range 8-400 K. The excitation photon energy was varied from the ultraviolet (4.5 eV) to the hard x-ray region (35 keV). It is found that as the excitation energy decreases the relative intensity of the low-energy luminescence band, attributed to the extrinsic emission of defect centers in CaW O4 and CaMo O4 crystals, increases. This observation is interpreted in terms of the tot...
