在水热条件下,以Y(NO3)3·6H2O,Eu2O3,NH4VO3,Na3C6H5O7·2H2O为原料合成了YVO4纳米微粒以及稀土离子Eu3+掺杂的YVO4:Eu纳米微粒,利用XRD,FE-SEM,TEM,HRTEM和SAED对所得产物的结构和形貌进行表征,并用FT-IR、F-4600对所得产物的光谱性质进行了分析.结果表明,产物为纯净的四方相YVO4,具有较为规则的饼状形貌,单个饼状YVO4纳米微粒的直径约为500nm.XRD图谱显示稀土离子Eu3+取代了Y3+进入YVO4晶体,但在纳米YVO4:Eu的荧光光谱上没有出现VO43-发射峰,这表明YVO4是良好的发光基质材料.水热合成方法简单易行,合成出的YVO4:Eu粒子荧光强度大且荧光强度稳定.
