Abstract
This paper reports experimental study on the development of cadmium tungstate scintillator material in the form of nanocrystal films through controlled sol-gel processing and pre-designed doping. We chose cadmium tungstate as a base material for doping and nanostructure development due to its excellent inherent photoluminescence property. In addition, our studies revealed that doping with Li+, B3+ and Bi3+ resulted in appreciably reduced grain size and porosity, leading to enhanced optical transmittance. Further analyses indicated that photoluminescence output changed significantly with dopants. The relationships between doping, defects and luminescence were discussed.
