摘要：

Ce3+-doped silicate phosphors (Mg2-xSiO4:xCe(3+), x = 0.001-0.007 mol) for NUV w-LEDs have been synthesized by solid-state reaction method at 1450 degrees C. The as-prepared samples have been characterized by XRD and fluorescence spectrophotometer, respectively. The XRD results show that the aim phase has been synthesized and doping Ce3+ has not resulted in impurity phase. This phosphor material exhibits a strong blue-violet emission (330-520 nm) under the near-ultraviolet radiation excitation. The average colorimetric coordinate of Mg2-xSiO4:xCe(3+) (x = 0.0025 mol) is (0.1508, 0.0694), locating in blue-violet region. We have obtained bright blue-violet light via pumping the sample by NUV light (lambda approximate to 365 nm), suggesting that this material can be potential as a NUV converting blue-violet phosphor for the NUV w-LEDs.
