摘要

采用一种简单有效的原位水热合成方法，使用石墨烯氧化物（GO）作为反应物和晶体生长基底成功制备出了还原氧化石墨烯/硒化锌（r-GO/ZnSe）纳米复合材料。采用X射线粉末衍射（XRD）、透射电子显微镜（TEM）、高分辨透射电镜（HRTEM）以及红外-可见光谱（FT-IR）等方法对r-GO/ZnSe纳米复合材料进行了检测。结果表明，平均粒径在30 nm的立方闪锌矿晶体结构的ZnSe粒子均匀分散在氧化石墨烯片层上，构成纳米复合结构。 UV-Vis光谱显示，纳米复合材料的光学吸收的起始波长在445 nm附近。PL光谱显示，纳米复合材料在470 nm附近存在一个很强的发射峰。这种石墨烯基纳米复合材料在白光二极管领域中有重要的应用价值。

Abstract

Reduced graphene oxide-ZnSe (r-GO/ZnSe) nanocomposites were successfully synthesized by an easy hydrothermal method. This process used the graphene oxide nanosheets as dispersant and two-dimensional growth template for ZnSe

resulting in the

in situ

formation of ZnSe nanoparticles on graphene oxide nanosheets and subsequent reduction of graphene oxide to r-GO. The samples were characterized by XRD

TEM

and FT-IR. The results show that the cubic ZnSe nanoparticles with the mean size of 30 nm distribute on r-GO sheets to form compact composites. UV-Vis absorption spectra indicate that the absorption edge of r-GO/ZnSe is at about 445 nm. PL spectra show a strong emission peak at 470 nm excited by 430 nm. The obtained r-GO/ZnSe nanocomposites may play important role in white LED field.
