    摘要:

    以甘氨酸作燃燒劑采用燃燒法制備Y2Zr2O7:Tb3+納米晶粉末。用X射線衍射儀（XRD）、高分辨透射電子顯微鏡（HRTEM）和熒光分光光度計對Y2Zr2O7:Tb3+納米晶的相結(jié)構(gòu)、形貌和發(fā)光性質(zhì)進行研究。結(jié)果表明：所得到的納米晶粒度均勻、結(jié)晶完好，屬于立方螢石結(jié)構(gòu)。發(fā)光光譜的測試表明：Tb3+呈現(xiàn)其特征綠色發(fā)射，最強峰位于542 nm處。Tb3+的摻雜摩爾濃度在0.5%~6%的范圍內(nèi)，3%為最佳摻雜濃度。

    Abstract:

    Y2Zr2O7:Tb3+ nano-phosphors were fabricated by combustion synthesis method using glycine as incendiary agent. X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM) and fluorescence spectrometer were used to characterize the phase structure, surface morphology and luminescence property of Y2Zr2O7:Tb3+ nano-phosphors. The results show that the prepared samples have uniform crystallinity and fine crystalline, with a cubic fluorite structure. Typical Tb3+ emission peaks were observed in the fluorescence spectra and the strongest emission at about 542 nm with green color corresponded to the 5D4--→7F5 transition. The doping concentration of Tb3+ was in the range of 0.5%-6%, with the optimum of 3%.
