Preparation and luminescence of Dy3+ doped glass-ceramics containing ZnMoO4

Dy3+ doped ZnMoO4 glass-ceramics was prepared by traditional melt crystallization method. The crystalline phase, microscopic morphology, transmittance, the optimal heat treatment condition and luminescence properties of the samples were discussed. The emission peaks are located at 482 nm, 574 nm and 663 nm due to F-4(9/2)-> H-6(15/2), F-4(9/2)-> H-6(13/2) and F-4(9/2)-> H-6(11/2) transitions of Dy3+ under 387 nm. When the doped concentration of Dy3+ exceeded 0.4%, it was proved that the multi-stage interaction between adjacent ions causes concentration quenching by calculating the critical distance between Dy3+. The chromaticity coordinate (CIE) showed the luminescence color of the samples in the white light region, indicating that Dy3+ doped glass-ceramics containing ZnMoO4 were expected to be applied in white-light emitting diode (w-LED).
