摘要

通过调整硅表面所修饰巯基的密度来控制吸附金种子的密度,利用种子周边相邻的材料控制其生长方向,直接在硅表面生长垂直金纳米棒自组装薄膜。用原子力显微镜对自组装薄膜的形貌进行表征,并检测薄膜对罗丹明R6G的表面增强拉曼光谱(SERS)效应。结果表明:垂直而有序的短棒在基底表面的自组装能够长期保持稳定,且序列越整齐其SERS效果越好。

Abstract

Vertical self-assembled films of Au nanorods on the silicon surface were obtained by adjusting the mercapto-group density of the self-assembled monolayers for the density of adsorbed seed particles and using adjacent materials to restrict the direction of seed growth.The morphology of the films was characterized by atomic force microscopy (AFM),and the SERS effect of the films on R6G was examined.The results shown that the self-assembly of the vertical and ordered short rods on the substrate surface can be stable for a long time,and not only the SERS effect of the substrate film on R6G was stronger with the increase of nanorods ranging regularity but also can be reused.
