In this work, instead of more common cation-substitution approach, we investigated the luminescence properties of Eu^2＋ and Mn^2 ＋ co-doped halophosphate solid solution Ca5（PO4）3（F0.8Cl0.2） via anion substitution synthesized by high temperature solid state reaction method. The formation of the solid solution was confirmed by X-ray diffraction （XRD） characterization, which indicates that the introduction of certain proportion of CI will not make significant change on the CaB（PO4）3F lattice, We also studied the energy transfer from Eu^2＋ to Mn^2＋ in the host so as to obtain white light emission via adjusting the doping concentrations of Eu^2＋ and Mn^2＋, The white light emission was achieved through combination of Eu^2＋ blue emission and Mn^2＋ red-orange emission with appropriate proportions. The results suggest that Ca5（PO4）3（F0.8Cl0.2）：0.01Eu^2＋＋,0.18Mn^2＋ could be a potential WLED phosphor working under ultraviolet excitation,展开更多
