Luminescence properties of Bi codoped and P codoped Ca3(VO4)2:Eu3+

Abstract

New red emitting phosphors, Ca3(VO4)2:Eu3+,Bi3+, Ca3((P,V)O4)2:Eu3+ were synthesized by low temperature solid-state reaction and characterized by X-ray diffraction, scanning electron microscopy, photoluminescence spectra and Fourier transform infrared spectroscopy. The results show that the red emission located at about 613 nm was ascribed to 5 D 0-7 F 2 transition of Eu3+. The effect of by Bi doping and by P doping was also investigated systematically.
