초록
Dy3+-doped N3Gd(PO4)2 phosphors were synthesized by high temperature solid-state reaction. The X-ray diffraction patterns and Fourier transform infrared absorption measurements were performed to characterize the synthesized phosphors. The excitation and emission spectra of Gd3+ and Dy3+ in Na3Gd(PO4)2 : Dy3+ were detected in the wavelength region from UV to visible. With increasing Dy3+ concentration, the Gd3+ emission at 313 nm due to the 6 P7/2 → 8 S7/2 transition decreases, while blue and green emissions due to the Dy3+ → 4 F9/2 4 H15/2, 13/2 transitions increase under excitation into the Gd3+ 6 I7/2 Level. The results indicate that the efficient energy transfer occurs from Gd3+ to Dy3+ in N3Gd(PO4)2 : Dy3+.
