摘要：

The Ba1.67Cat--, (B306)2 Eu', Mr42+ (x = 0, 0.03, 0.06, 0.15) phosphors were synthesized by high temperature solid-state reaction, and their phase composition and luminescence properties were studied. In these phosphors, Eu2+ locates at the crystal sites of Ba2+ and Ca2+ ions. Under 317 nm UV light excitation, the 5d -> 4f transition of Eu2+ forms a broad blue emission band with a peak at 450 nm. With the energy transfer from Eu2+ ions, Mn2+ ions emit a broad red band with the peak at 600 nm. The mixture of the broad blue emission and a broad red emission forms an approximate white light with the CIE chromaticity (x=0. 371, y=0. 282). The phosphors can be excited effectively by UV light in the range of 250-400 nm, so they are the potential candidates for single white light-emitting phosphor excited by UV-LED.
