摘要：
ScVO4:Eu3+, Bi3+, Al3+ phosphors were synthesized by solid-state reaction at 1000 ℃ for 6 h. The samples were characterized by X-ray diffraction, FESEM, emission and excitation spectra. Under 315 nm excitation, strong salmon can be observed, which result from the emission band in 590~620 nm and the maximum emission peak in 615 nm. The incorporation of a small amount of Al3+ can distinctly enhance the luminescence of the ScVO4:Eu3+, Bi3+ phosphors, while the excess amounts of Al3+ can make its luminescence weaker. The intensity of (Sc0.81Eu0.05Bi0.10 Al0.04)VO4 phosphor is the strongest, improved 30 times than undoped (Sc0.85Eu0.05Bi0.10)VO4 phosphor. © 2015, Science Press. All right reserved.
