Abstract: | A novel green phosphor Tb3+ doped AlPO4 was synthesized by conventional solid-state reaction method. The phosphor showed prominent luminescence in green due to the 5D4-7F5 transition of Tb3+. Structural characterization of the luminescent material was carried out with X-ray powder diffraction (XRD) analysis. The XRD measurements indicated that there are no crystalline phases other than AlPO4. Luminescence properties were analyzed by measuring the excitation and photoluminescence spectra. Photoluminescence measurements indicated that the phosphor exhibited bright green emission at about 542 nm under UV excitation. It is shown that the 3 mol% of doping concentration of Tb3+ ions in AlPO4:Tb3+ phosphor is optimum. The measured chromaticity for the phosphors AlPO4:Tb3+ under UV excitation is (0.32, 0.53). |
