The structure of the phosphors was characterized by the X-ray diffraction (XRD), which was corresponded to JCPDS card with # 25-0828. The photoluminescence properties of the prepared products were characterized by the excitation and emission spectra. The energy transfer from Tb3+ to Eu3+ in NaGd(MoO ) phosphors was confirmed. 4 2 Keywords Hydrothermal Synthesis, NaGd(MoO ) , Tb3+, Eu3+ 4 2 NaGd(MoO ) : Tb3+, Eu3+荧光粉的水热合成及 4 2 发光性质研究 丁 瑶 哈尔滨师范大学，物理与电子工程学院，黑龙江 哈尔滨 收稿日期：2015年12月11 日；录用日期：2015年12月27 日；发布日期：2015年12月30 日 文章引用: 丁瑶.
