Abstract
Tb3+-Sm3+ co-doped Sr9Gd(PO4)5(SiO4)F2 (SGPSF) phosphors were prepared through a solid-state reaction, and their luminescence properties as well as energy transfer mechanism have been investigated in detail. The SGPSF:Tb3+, Sm3+ phosphors system could be efficiently excited at wavelengths ranging from 200 to 500Â nm, which is well matched with the spectra of near ultraviolet chips. The emission of SGPSF:Tb3+, Sm3+ phosphor covers the entire visible region with sharp peaks in the blue, green, and red regions. The emission color of SGPSF:Tb3+, Sm3+ could be adjusted from green (0.275, 0.378) to red (0.519, 0.295) by controlling the doping content of Sm3+/Tb3+.
