Abstract

Nanowires of CuS, ZnS, CuSe, and ZnSe, with diameters in the 5-150-nm range and high aspect ratios, have been prepared with the use of surfactants and characterized by X-ray diffraction and electron microscopy. Electronic absorption spectra and photoluminescence spectra of chalcogenide nanowires have been studied. The spectra show blue-shifts compared with those of bulk samples.

摘要

已使用表面活性剂制备出直径在5至150纳米范围内且长径比高的硫化铜、硫化锌、硒化铜和硒化锌纳米线，并通过X射线衍射和电子显微镜对其进行了表征。研究了硫族化物纳米线的电子吸收光谱和光致发光光谱。与块状样品的光谱相比，这些光谱显示出蓝移。
