英文摘要The luminescence properties of polyphosphates NaEu (x) Gd(1-x)(PO3)(4) (x = 0-1.00) and the energy transfer from Gd3+ to Eu3+ were studied. In undoped NaGd(PO3)(4) sample, the photon cascade emission of Gd3+ was observed under S-8(7/2) -> (6)G(J) excitation (201 nm) in which the emission of a red photon due to (6)G(J) -> P-6(J) transition is followed by an ultraviolet photon emission due to P-6(J) -> S-8(7/2) transition. When part of Gd3+ ions in the host NaGd(PO3)(4) were substituted by Eu3+ ions, the NaGd(PO3)(4):Eu3+ sample showed intensive red emission under 172-nm vacuum-ultraviolet (VUV) excitation which is suitable for mercury-free fluorescent lamps and plasma display panel applications. Based on the VUV-visible spectroscopic characteristics and the luminescence decay properties of NaGd(PO3)(4):Eu3+, it was found that the quantum cutting by a two-step energy transfer from Gd3+ to Eu3+ can improve the red emission of Eu3+ ions under VUV excitation but only a part of the excitation energy in the excited P-6(J) states within Gd3+ ions can be transferred to Eu3+ ions for its red emission, and the nonradiative energy transfer efficiencies from the excited P-6(J) states within Gd3+ to Eu3+ were calculated.
