摘要

研究了ZnO纳米棒阵列的表面增强拉曼散射(SERS)特性。研究发现，在znonr和附着的探针分子之间实现有效的光诱导电荷转移是SERS的关键前提。从ZnO纳米结构上可以观察到10-7 M浓度的染料(Bu4N)2[Ru(dcbpyH)2-(NCS)2]的SERS。

SERS from ZnO nanorod arrays and its application for detecting N719

The surface-enhanced Raman scattering (SERS) from ZnO nanorod arrays (ZnONRs) was investigated. It was found that the realization of the efficient photoinduced charge transfer between the ZnONRs and the attached probe molecules is a critical prerequisite for the SERS. The SERS of the dye (Bu₄N)₂[Ru(dcbpyH)₂-(NCS)₂] with 10^-7 M concentration can be observed from the ZnO nanostructures.
