摘　　要：在互不相溶的离子液体-水(ILs-H2O)界面合成了由Ag颗粒组成的薄膜。采用不同的ILs,在1-癸基-3-甲基咪唑六氟磷酸盐-水([C10mim][PF6]-H2O)、1-癸基-3-甲基咪唑双三氟磺酰亚胺盐-水([C10mim][Tf2N]-H2O)和1-癸基-3-甲基咪唑四氟硼酸盐-水([C10mim][BF4]-H2O)界面分别合成了由Ag纳米片、纳米带和立方颗粒所组成的薄膜。所制备的Ag薄膜能够直接用作表面拉曼增强(SERS)研究的活性底物。而且,由纳米片以及纳米带组成的Ag薄膜显示出较强的SERS效应。At the immiscible ILs-H2O interface, the Ag particles with different shapes are generated and in situ assembled into Ag films. By employing different ILs, Ag films built up by large Ag nanoplates,long nanobelts and cubes can be easily obtained at [ C10 mim] [ PF6 HH20, [ Clo mim] [ Tf2N]-H2O, and [ C10 mim] [ BF4 I-H20 interface, respectively. The surface enhanced Raman scattering （SERS） studies of the as-prepared films are performed by using 4- ATP as a molecule probe. The results show that the long nauobeh and large nanoplate Ag films exhibit highly SERS responses.
