中文摘要：

采用复合氢氧化物媒介法制备了Ba3V2O8∶Eu3＋纳米花。利用SEM-EDS、XRD、TEM和XPS对晶体的形貌和尺寸、结构和化学组成进行了表征。结果表明产物是由厚度约20nm的纳米片组成的花状Ba3V2O8∶Eu3＋纳米晶体。荧光光谱测定发现Ba3V2O8∶Eu3＋晶体在紫外光和蓝光激发下都能产生591和612nm 2个强发射峰,表明其具有将紫外光和蓝光转换成红光的能力,可以进一步应用于光转换和光发射领域。探讨了Ba3V2O8∶Eu3＋纳米花的发光机理。

英文摘要：

Ba3V2O8∶Eu3＋ nanoflowers were obtained by the composite hydroxide mediated（CHM） method.Scan electron microscope and transmission electron microscope displayed that the flower-shaped crystals were composed of nanosheets with thickness of about 20nm.Photoluminescence spectrum of the Ba3V2O8∶Eu3＋ nanoflowers exhibited red emission centered at 591 and 612nm,which showed function of red light conversion.The mechanism of light emission of the Ba3V2O8∶Eu3＋ nanoflowers was discussed.
