运用简单的一步反应水热法制备了石墨烯-硒化银(G-Ag2Se)纳米复合材料.用X射线粉末衍射(XRD)、傅里叶变换红外光谱(FTIR)和透射电子显微镜(TEM)等手段对所得产物进行了系统的表征.结果表明,反应体系中,硒化银纳米粒子的形成与氧化石墨烯的还原同时进行.石墨烯氧化物被充分地还原为石墨烯,并且Ag2Se纳米粒子均匀地分布在石墨烯的片层上,形成纳米复合材料.对所制备的G-Ag2Se纳米复合材料的光学性质也进行了研究.

We report a facile and efficient strategy for the preparation of graphene-Ag2Se nanocomposites.The treduction of graphene oxide (GO) to graphene was accompanied by the formation of Ag2Se particles on the surface of graphene nanosheets.The results of X-ray diffraction (XRD) and Fourier transform infrared (FTIR) confirmed the efficient reduction of GO.Transmission electron microscopy (TEM) images of the sample revealed the morphology of the architecture of graphene-Ag2Se hybrid.Photoluminescence (PL) measurement was further employed to study the optical properties of the nanocomposites.The results show that the graphene-Ag2Se nanocomposites can be prepared by a simple hydrothermal method,and Ag2Se particles are well distributed on the graphene nanosheets.
