Abstract

A color-tunable NaCaY(PO4)2:Eu2+, Mn2+ was synthesized by a solid state reaction. NaCaY(PO4)2 crystallizes in the hexagonal structure system with space group of P6222 and Z = 1. The NaCaY(PO4)2:Eu2+ exhibits blue-greenish emission and broad excitation bands corresponding to the allowed fd electronic transition of Eu2+. In addition, via the design of efficient energy transfer from Eu2+ to Mn2+, a high quality of white-emitting light could be generated in the optimized composition of NaCaY(PO4)2:1%Eu2+, 0.5%Mn2+ with CIE coordinates of (0.3389,0.3531) and CRI of 82, which is superior than that of blue chip and YAG phosphors. The results indicate that as-synthesized NaCaY(PO4)2:Eu2+, Mn2+ phosphors exhibits the potential to be an n-UV convertible phosphor.
