In this work, a group of Li2Zr(PO4)2 doped with various Dy3+ concentrations were prepared utilizing the solid state reaction method. The crystalline phases were identified by the implement of XRD as well as Rietveld refinement. The surface morphology, elemental analysis and vibrational properties were characterized by SEM, EDX and FTIR techniques. Upon the irradiation of 349 nm, all the phosphors exhibited blue-green light emission with the primary peak at 488 nm. Furthermore, the optimal doping concentration of Dy3+ ion was determined as 2 mol%, and the mechanism of energy transfer between two adjacent Dy3+ ions was dominated by the dipole-dipole interaction. The possible lattice sites occupied by Dy3+ ions were investigated via the fitting function type of decay curves. The calculated CIE chromaticity coordinate of Li2Zr(PO4)2:Dy3+ (2 mol%) phosphor verified that its emission light was located in the blue-green region. The aforesaid results demonstrated that the Li2Zr(PO4)2:Dy3+ phosphors could be potential candidates for application in display and solid state lighting.
