英文摘要	The phosphors in the system Sr2-x-yP2O7:xEu(2+),yMn(2+) were synthesized by solid-state reactions and their photoluminescence properties were investigated. These phosphors have strong absorption in the near UV region, which is suitable for excitation of ultraviolet light emitting diodes (UVLEDs). The orange-reddish emission of Mn2+ in these phosphors can be used as a red component in the tri-color system and may be enhanced by adjusting the Mn2+/EU2+ ratio. The energy transfer from Eu2+ to Mn2+ is observed with a transfer efficiency of similar to 0.45 and a critical distance of similar to 10 angstrom. The results reveal that Sr2-x-yP2O7:xEu(2+),yMn(2+) phosphors could be used in white light UVLEDs. (C) 2007 Elsevier Ltd. All rights reserved.
