Synthesis and Spectra Properties of YVO4:Eu Nanoparticles
Source abstract
Abstract
在水热条件下, 以Y(NO 3 ) 3 ·6H 2 O, Eu 2 O 3 , NH 4 VO 3 , Na 3 C 6 H 5 O 7 ·2H 2 O为原料合成了YVO 4 纳米微粒以及稀土离子Eu 3+ 掺杂的YVO 4 :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YVO 4 , 具有较为规则的饼状形貌, 单个饼状YVO 4 纳米微粒的直径约为500nm. XRD图谱显示稀土离子Eu 3+ 取代了Y 3+ 进入YVO 4 晶体, 但在纳米YVO 4 : Eu的荧光光谱上没有出现VO 4 3- 发射峰, 这表明YVO 4 是良好的发光基质材料. 水热合成方法简单易行, 合成出的YVO 4 :Eu粒子荧光强度大且荧光强度稳定.
