摘要：

Tm3+ and Dy3+ co-doped YAl3(BO3)(4) phosphors were synthesized by the solid state reaction method. The phosphors show blue emission band centered at 450 nm originated from the transition of Tm3+ ions and yellow band of 573 nm ascribed to Dy3+ ions excited by UV light. The emission colors are tuned from blue to white and ultimately to yellow through concentration variation of luminescent centers of Tm3+ and Dy3+ in YAl3(BO3)(4) phosphors. A white light can be achieved from YAl3(BO3)(4):0.03Tm(3+), 0.09Dy(3+) phosphor with chromaticity coordinates of (0.310, 0.331) under excitation at 365 nm. The results show that the single-phased YAl3(BO3)(4):Tm3+, Dy3+ phosphors are a potential phosphors for current illuminated light source. (C) 2012 Elsevier GmbH. All rights reserved.
