Al3+掺杂ScVO4:Eu3+,Bi3+荧光粉的制备及发光性质
Synthesis and Luminescence of ScVO4:Eu3+,Bi3+,Al3+ Phosphors
摘要
Abstract
ScVO4:Eu3+,Bi3+,Al3+ phosphors were synthesized by solid-state reaction at 1 000℃ 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. 81 Eu0. 05 Bi0. 10 Al0. 04 ) VO4 phosphor is the strongest, improved 30 times than undoped ( Sc0. 8 5 Eu0. 05 Bi0. 10 ) VO4 phosphor.关键词
