Paper Abstract

Cadmium Tungstate is a complex oxide which gains considerable attention as a scintillator material. The material has high radiation hardness and in crystalline form is highly efficient. It is also non-hydroscopic, unlike the more efficient thallium doped NaI crystal. A processing technique utilizing sol gel technology has been successfully applied to this system for the first time to allow for more precise stoichiometry control, as well as to produce thin films more easily and cheaply than other methods. The as-produced material consists of single phase, stoichiometric nano-crystallites of cadmium tungstate and shows photoluminescence at 480nm. The material was characterized by X-ray diffraction, SEM and PL analysis.
