Orthovanadates AVO4 (A is a trivalent rare earth element) have recently emerged as promising optical materials for birefringent solid-state laser applications, cathodoluminescent materials, thermophosphors, scintillators, and photocatalysis materials [1].In this type of crystals, CeVO4 has been attracted much more attention because of its particular 4f-5d electronic transition of Ce3+ ion.
