Single-phase Ba5(PO4)3Cl:Ce3+,Tb3+ (BPCl:Ce3+,Tb3+) samples have been synthesized via solid-state reaction method. The phase structure and luminescence properties are characterized using powder X-ray diffraction (XRD), photoluminescence excitation and emission spectra. Effective energy transfer occurs from Ce3+ to Tb3+ due to the observed spectral overlap between the emission band of Ce3+ and the excitation band of Tb3+. Ce3+/Tb3+-codoped Ba5(PO4)3Cl shows more intense yellowish-green light compared to that of Tb3+-doped sample under UV light excitation.

Tb3+, Er3+co-doped K2GdZr (PO4)3samples were prepared by solid-state reaction method and their photoluminescence (PL) properties were investigated in ultra-violet (UV) and vacuum ultra-violet (VUV) region. The results indicate that the energy transfers from Er3+to Gd3+and from Gd3+to Tb3+required for occurring of visible quantum cutting through down-conversion are efficient. In this cooperative energy transfer process, Gd3+is used as an intermediate of energy transfer between Er3+and Tb3+. The optimal quantum efficiency (QE) of this co-doped system K2GdZr (PO4)3: Er3+, Tb3+phosphor reached to 110%, suggesting a potential visible quantum cutting phosphor in practical application.
