以尿素为燃料,硝酸锌作为锌源和氧化剂,硝酸铕提供掺杂离子,以微波诱导燃烧法合成了铕掺杂氧化锌纳米材料.并考察了尿素用量、微波功率、稀土离子掺杂量对产物性能的影响.采用XRD,SEM,PL等测试方法对产物进行了表征.实验结果表明:当微波功率为340 W,燃料恰好完全反应,反应物硝酸锌与硝酸铕物质的量之比为1∶1时得到产品的结晶度高,光学性能最好；根据谢乐公式计算一次粒子平均粒径约为50 nm,晶相与标准立方相氧化锌衍射峰非常吻合.PL测试结果表明,362 nm处出现的紫外发射峰是由于氧化锌的紫外发射峰发生蓝移造成,而451 nm、468 nm、482 nm处的蓝光发射峰可能是由于氧空位形成的浅施主能级向价带跃迁引起的.
