摘要The luminescence compound (Y-x,Gd0.95 - x)BO3:Eu-0.05(3+) with a single phase hexagonal crystal structure has been synthesized by the solid state reaction. The cla value is linearly decreasing when the ratio of Y3+/Gd3+ is increasing, which indicates that the solid-solution of YBO3 and GdBO3 is forming. The two symmetric stretching vibration peaks of the BO4 anion at 866 and 912 cm (- 1) in the FTIR spectrum exist in two forms in the solid solutions. The local symmetric environment surrounding the Eu3+ ion was lowered with the decrease of Y3+/Gd3+ ratio. The host absorption band and Eu3+ - O2 - charge transfer band were observed in the excitation spectra of (Y-x,Gd0.95 - xBO3:Eu-0.05(3+). In particular, the relative intensity of Eu3+ - O2 - charge transfer band sharply decreased when the ratio of Y3+/Gd3+ increased was identified by the variation of local symmetric environment around Eu3+. The ratio of the fluorescence intensity of D-5(0) -> F-7(2) transition and D-5(0) -> F-7(1) transition (R/O ratio) is decreasing with the increasing of Y3+ content. (c) 2007 Elsevier B.V.
