摘    要:The doping effects of La^3+, Gd^3+ and Lu^3+ on the crystal structure and luminescence properties of (Yo96-x LnxCe0.04)3Al5O12(Ln = Gd, La, Lu) phosphors were studied. The X-ray diffraction patterns presented that with the inerease of the doping concentrations of La^3+ and Gd^3+ ions, the d-value of (Y0.96-xLnxCe0.04)3Al5O12 (Ln = Gd, La) inereased and the larger the doping ion, the stronger the effect would be. The doping amount causing phase transition in (Y0.96-xLnxCe0.04)3Al5O12 decreased with the inerease of the ionic radii of the doping lanthanide ions (La^3+: 0.106 nm, Gd^3+: 0. 094 nm, Lu^3+ : 0.083 nm). The bigger doping ion of Gd^3+ made the emission of (Y0.96-xGdxCe0.04)3Al5O12 move to red spectral region, but the smaller one of Lu^3+ made it blue.

Abstract:The doping effects of La3 , Gd3 and Lu3 on the crystal structure and luminescence properties of (Y0.96-xLnxCe0.04)3Al5O12 (Ln=Gd, La, Lu) phosphors were studied.The X-ray diffraction patterns presented that with the increase of the doping concentrations of La3 and Gd3 ions, the d-value of (Y0.96-xLnxCe0.04)3Al5O12 (Ln=Gd, La) increased and the larger the doping ion, the stronger the effect would be.The doping amount causing phase transition in (Y0.96-xLnxCe0.04)3Al5O12 decreased with the increase of the ionic radii of the doping lanthanide ions (La3 0.106 nm, Gd3 0.094 nm, Lu3 0.083 nm).The bigger doping ion of Gd3 made the emission of (Y0.96-xGdxCe0.04)3Al5O12 move to red spectral region, but the smaller one of Lu3 made it blue.
