摘要

A series of Dy ³⁺ ion doped Sr ₂ CaWO ₆ phosphors with double perovskite structure were synthesized by traditional high temperature solid-state method. It was found that there is significant energy transfer between Dy ³⁺ and the host lattice, and the intensities of emission peaks at 449 nm (blue), 499 nm (cyan), 599 nm (orange), 670 nm (red), and 766 nm (infra-red) can be changed by adjusting the concentration of dopant amount of Dy ³⁺ ion in Sr ₂ CaWO ₆ . The correlated color temperature of Dy ³⁺ ion doped Sr ₂ CaWO ₆ phosphors can be tuned by adjusting the concentration of Dy ³⁺ ion. Upon optimal doping at 1.00 mol% Dy ³⁺ , white light with chromaticity coordinate (0.34, 0.33) was emitted under excitation at 310 nm. Thus, single composition white emission is realized in Dy ³⁺ doped Sr ₂ CaWO ₆ .
