以NaVO3、Zn(NC3)2·6H2O为原料,采用水热法合成了铕离子掺杂Zn2 (OH)3 VO3纳米晶体.运用X射线粉末衍射、扫描电子显微镜、荧光测试仪对纳米晶进行了表征,研究了水乙醇体系不同pH值对产物晶相、微观形貌及荧光性能的影响.在溶剂体系pH值为7～10时,得到片状的Zn2 (OH)3 VO3,而在pH值为4～6和11～12时得到Zn3 (OH)2V2O7·2H2O,表明强酸性和强碱性的溶剂体系都不太适合Zn2 (OH)3 VO3的合成,而最佳的合成体系为中性偏碱性;荧光测试表明在pH=10的水乙醇体系下合成的Zn2(OH)3VO3∶8％Eu3+纳米片的荧光性能最好,其中发射主峰位于612 nm处.
