摘要：

The fluorescence properties of Eu3+ and Tb3+ doped Na6La(BO3)(3), Na6Gd(BO3)(3), Na6Y(BO3)(3), Na-6(Gd,Y)(BO3)(3) powder phosphors are reported. These phosphors display fluorescent RED and GREEN colours when droped with Eu3+ and Tb3+ ions, respectively. The best fluorescence performance was consistantly observed from the Na-Gd based hosts. The photoluminescence and spectra were analysed by evaluating colour coordinates, relative intensity ratios, and stimulated emission cross-sections.
