摘要

用水热法以Zn(NO

)

O和NaOH为原料

分别以十六烷基三甲基溴化铵(CTAB)、十二烷基硫酸钠(SDS)、聚乙烯吡咯烷酮-K30(PVP-K30)、聚乙二醇400(PEG400)、乙二胺四乙酸(EDTA)为添加剂

制备钼掺杂的纳米ZnO。扫描电镜(SEM)结果表明

通过改变添加剂的种类可以合成不同形貌钼掺杂的ZnO;X射线衍射(XRD)结果表明

掺杂的ZnO纳米粉体为六方纤锌矿结构

随着钼掺杂浓度的增加

衍射峰强度明显增大

结晶质量得到明显改善;室温下的光致发光(PL)图谱表明

掺杂的样品在385 nm处有一紫光发射峰

在约572 nm处有一绿发光射峰

Mo掺杂后明显提高了样品的发光强度。

Abstract

Different contents of molybdenum-doped ZnO were prepared by hydrothermal method

using Zn(NO

)

O and NaOH as precursors

CTAB

SDS

PVP-K30

PEG400

EDTA as additive. SEM images show that various morphologies of molybdenum doped ZnO can be obtained by changing the types of additives. XRD results indicate that the doped ZnO were wurtzite structure. With the increasing of the molybdenum concentration

the diffraction peak intensity are significantly enhanced and the crystalline quality is improved. There are violet emission peak at 385 nm and green emitting at 572 nm in the PL spectra of ZnO:Mo. The luminous intensity varies with the molybdenum concentration.
