【摘要】 以氧化钆（Gd₂O₃）、氧化铕（Eu₂O₃）、钼酸铵（H₈Mo N₂O₄）、柠檬酸（C₆H₈O₇）为原料，采用超声波辅助溶胶-凝胶法成功制备了Gd₂（Mo O₄）₃:Eu³⁺荧光粉发光材料。讨论了Eu离子掺杂浓度和前驱体是否煅烧对荧光材料性能的影响，利用X-射线衍射仪（XRD）、扫描电子显微镜（SEM）、荧光光谱仪（LS）对材料进行表征和分析。结果表明：在403 nm最优激发波长激发下，材料的发射峰位于470～530nm之间，Eu离子掺杂浓度及是否煅烧都会对材料的形貌和发光性能产生影响。更多还原

【Abstract】 Gadolinium oxide（Gd₂O₃）,europium oxide（Eu₂O₃）,ammonium molybdate（H₈MoN₂O₄）,citric acid（C₄H₂O₂）were used as raw materials,Gd（₂MoO₄）₃:Eu³⁺luminescent material were prepared by ultrasound-assisted gel-gel method.The effects of Eu ion molar number and whether they were calcined are discussed.Materials were characterized and analyzed using X-ray diffractor（XRD）,scanning electron microscope（SEM）and Fluorescence spectrometer（LS）.The results show that:with the optimal excitation at 403 nm,the emission peaks of the material are located between 470 and 530nm,the amount of Eu ionic and whether calcined affect the morphology and luminescente properties of the material.更多还原
