英文摘要: In present work, K2Y1-xZr(PO4)3:Prx 3+ (0.01&lex&le0.05) samples were prepared by solid-state reaction method and their photoluminescence properties were investigated in ultra-violet (UV) and vacuum ultra-violet (VUV) region. The photon cascade luminescence (PCL) of Pr3+ had been observed. All the results indicate that, in this Pr3+-doped K2YZr(PO4)3 phosphor, even if the 1S0 state is higher than the lowest 4f5d energy level, the photon cascade emission (PCE) process for Pr3+ still could occur under 147 nm and 234 nm (4f15d1 state) excitation. Therefore, K2YZr(PO4)3 was an ideal host for Pr3+ to implement the PCE process successfully. © (2013) Trans Tech Publications, Switzerland.
