摘要：

The VUV-vis spectroscopic properties of Gd3+ in Na(Y,Gd)FPO4 are reported. The photon cascade emission was observed under S-8(7/2) -> (6)G(J) excitation in which (6)G(J) -> P-6(J), I-6(J) emissions of Gd3+ in the orange/red and near-IR range are followed by ultraviolet emission of P-6(J) -> S-8(7/2) transitions. We demonstrate systematically the emission decays and concentration-quenching characteristics of (6)Gj -> (6)Pj and P-6(J) -> S-8(7/2) transitions under excitation into (6)G(J) levels. The effect of temperature on the (6)G(J) -> P-6(J) emissions is also presented.
