Scintillator with ZnWO4 single crystal

摘要

A scintillator formed of a ZnWO4 single crystal having an absorption coefficient less than or equal to 1.8 cm-1 for the light having a wavelength of 520 nm is disclosed which has a luminescence wavelength of 480 nm and therefore can be combined with a photodiode, and which is high in radiation detection sensitivity, short in decay time, and specifically suitable for use in computed tomography.
