Optical Properties of One-dimensional Silicon Nanomaterials

硅纳米线与硅纳米管是两种重要的一维硅纳米材料,由于具有量子限制效应等性能在光电子器件方面具有潜在的应用前景。总结了近年来硅纳米线在光学特性方面的研究进展,重点介绍了本征硅纳米线、掺杂硅纳米线及硅纳米线阵列的光致发光光谱(PL)的最新进展情况,同时涉及了硅纳米管在PL发射光谱方面的研究结果。

Silicon nanowires and silicon nanotubes are two kinds of important one-dimensional silicon nanomaterials exhibiting a potential application prospect in the optoelectronic field owing to the quantum confinement effect. The recent studies on the optical properties of silicon nanowires mainly including the photoluminescence （PL） spectra of intrinsic~ nanowires, doped silicon nanowires and silicon nanowires array are reviewed in detail in this paper. In addition, the research development of silicon nanotubes （SiNTs） on PL spectra and the development direction are also introduced and discussed.
