| 摘 要： | 采用溶胶-凝胶法,在温和条件下以无水乙醇做反应溶剂制备出了Eu3+掺杂的ZnO纳米粒子,粒子呈纺锤体形,长度约为70nm,宽度为40nm,长径比为1.8。XRD分析表明,ZnO∶Eu粒子为六方晶系结构,结晶良好,Eu3+的掺杂并没有改变其晶型结构。通过EDS得到了晶体中Eu3+与Zn2+的物质的量的比;通过荧光光谱仪测定其荧光性能,结果表明,其荧光光谱具有2个Eu3+的特征峰,分别位于595nm和617nm,且在n(Zn2+)∶n(Eu3+)=100∶3时,Eu3+特征峰最强;通过对样品荧光光谱的分析,证明了ZnO基质和Eu3+发光中心存在能量传递。

| Abstract: | ZnO∶Eu nanoparticles were prepared by a sol-gel method.They were characterized by XRD and fluorescent measurements.XRD analysis revealed that the nanoparticles are hexagonal structure of zincite,with an average length of 70nm and width of 40nm.The Eu 3+ dopant does not change the crystalline structure of ZnO.The optimized emission intensity of Eu 3+-doped ZnS nanoparticles is obtained at 3.0% of Eu 3+ concentration with the emitting peaks centered at 595nm and 617nm.The photoluminescence was detected and energy transfer from the host to Eu 3+ ions was observed. |
