Photoluminescence and Photocatalytic Activity in Ca2+ and Dy3+ Co-doped ZnWO4 System

Abstract

Abstract.Ca 2+ and Dy 3+ co-doped ZnWO 4 system was synthesized successfully via high temperature solid-state reaction. The photoluminescent, X-ray diffraction (XRD), and photocatalytic properties of the phosphors had been studied systematically. , which could be ascribed to more electron-hole pairs generated and the combination of electrons and holes decreased in the co-doped phosphors. Thus, resulting in the increase of photocatalytic activity.
