CdS one-dimensional nanoforms such as nanowires, nanoribbons, network-like nanowires, pearl necklace type nanowires, helical-like nanowires, and nanowire arrays were formed on Si substrates by a simple thermal evaporation route. The shapes of the one-dimensional CdS nanoforms were controlled by varying the experimental parameters such as temperature and position of the substrates. Formation of the CdS one-dimensional nanoforms was initiated by the Au catalyzed vapor-liquid-solid technique, whereas the vapor-solid process played a crucial role in defining the shapes of the nanoforms. Different optical characterizations such as optical absorbance, photoluminescence, and Raman spectroscopy were adopted to explore the physical and structural quality of these CdS nanoforms.
通过简单的热蒸发途径，在硅衬底上形成了硫化镉（CdS）的一维纳米结构，如纳米线、纳米带、网络状纳米线、珍珠项链型纳米线、螺旋状纳米线和纳米线阵列。通过改变诸如衬底温度和位置等实验参数，可控制一维CdS纳米结构的形状。CdS一维纳米结构的形成是由金催化的气-液-固技术引发的，而气-固过程在确定纳米结构的形状方面起着关键作用。采用了不同的光学表征方法，如光吸收、光致发光和拉曼光谱，来探究这些CdS纳米结构的物理和结构质量。
