中文摘要：

石墨结构层包嵌铜纳米薄片是一种纳米尺度的复合材料,结构为铜纳米片被机械包嵌在石墨碳网之间.在其Raman光谱中,E2g2模的振动频率出现了红移,表明铜纳米薄片外部原子将部分电荷转移给了碳网,这与X射线光电子能谱分析结果一致.由1阶和3阶石墨层间化合物前驱体还原的样品,其Raman光谱具有弯曲碳网的特征,这可能来自薄片边缘的卷曲.前驱体的Raman光谱与其他受主型石墨层间化合物的Raman光谱一致.

英文摘要：

Graphene encapsulated copper nanoplates（GECNPs） is a composite in nanometer scale,and its structure is alike a sandwich that the copper nano-plates are contained in graphite gallery.The vibration frequency of E2g2 mode was red shift in the Raman spectra of graphene encapsulated copper nano-plates.It revealed that the partial charge of outer atoms of the copper nano-plate encapsulated in graphite gallery had been transferred to the hexagonal carbon nets and this result was coincident with that of X-ray photoelectron spectroscopy.The Raman spectra of two samples which had been reduced from the graphite intercalation compounds with stage 1 and stage 3 showed typical characterizations of curved carbon nets,and its origin may be due to the extreme thin frizzy edges for the flakes of GECNPs.The Raman spectra of precursors were similar to that of acceptor type graphite intercalation compounds.
