Scintillation study of ZnWO4 single crystals

Abstract

Scintillation characteristics of the Czochralski-grown ZnWO4 single crystal were studied. This crystal, with light red-brown color, exhibits a maximum luminescence wavelength of 480 nm under excitation at 254 nm. The total luminescence output under x-ray excitation at 254 nm. The total luminescence output under x-ray excitation was found to be 2.3 times larger than that of the best Bi4Ge3O12 at room temperature with small afterglow.
