摘要
采用反相微乳液在水热条件下,制备出了片状的氧化锌纳米材料,并掺杂少量稀土镧元素,研究了掺杂量对纳米氧化锌光学性能的影响,利用X射线衍射(XRD)、扫描电镜(SEM)和荧光光谱分析(PL)对所得样品进行了表征,结果表明镧的掺杂可以对纳米氧化锌的光性能有积极的影响,掺杂量为La/Zn at.%=0.025时,发光峰强度较强.
La-doped ZnO nanosheets were synthesized via hydrothermal microemulsion method. The effect of doping on the optical properties of nanosized ZnO was studied. Structures of the as-synthesized samples were characterized by X-ray diffraction （XRD） ,SEM and photoluminescence（PL） spectra. The results showed that lanthanum doping had an positive effect on photoluminescene of nanosized ZnO. There was strong emission peak when La/Zn （at. %） was 0. 025.
