Ba2 SiO4：Ce3+,Mn2+荧光粉的制备与光谱性质
Preparation and Photoluminescence Properties of Ba2 SiO4:Ce3+,Mn2+ Phosphor
摘要
Abstract
The phosphors Ba2SiO4∶xCe3+,yMn2+(x =0 -0. 2, y =0 -0. 15) were synthesized through the solid-state reaction technique. The structure, photoluminescence properties of these phosphors were described. Under the excitation of UV light, the emission spectra of Ba2 SiO4∶xCe3+show broad band around 384 nm. The emission spectra of Ba2 SiO4∶ Mn2+ show broad band around 376 nm, and the red emission is very weak. The red emission band located at around 606 nm is strongly enhanced in Ba2SiO4∶xCe3+,yMn2+, which is arised from 4T1(4G)-6A1(6S) transition of Mn2+. The results show that a part of the energy of Ce3+ ion is transferred to Mn2+ ion and sensitizes the luminescence of Mn2+ ion effectively. When the mole fractions of Ce3+ and Mn2+ are 0. 2 and 0. 075, the red emission around 606 nm is the strongest.关键词
