Good-quality SERS spectra of Rh6G on this nanowire arrays were observed, which demonstrated the SERS intensity depending on the wires length emerged above the surface, however the Raman shift was not affected by the surface condtion.

• Rh6G分子吸附在此基底上的SERS谱表明，SERS信号相当好，SERS谱强度与银纳米线在表面的显露高度有关，而其拉曼频移不受表面状态的影响。
