摘要

我们报道了单CdS纳米线和纳米片的拉曼散射结果。单纳米线表面增强拉曼散射显示出强一阶纵向光学(1LO)声子和弱2LO声子。相比之下，单个纳米片的拉曼散射显示出明显增强的2LO声子和几个额外的多声子。

Surface Enhanced Raman Scattering from Single CdS Nanowires and Nanosheets

We report Raman scattering results of single CdS nanowires and nanosheets. Surface enhanced Raman scattering from a single nano wire reveals a strong first-order longitudinal optical (1LO) phonon and a weak 2LO phonon. In contrast, Raman scattering from a single nanosheet shows a significantly enhanced 2LO phonon and several additional multiphonons.
