采用热蒸发法制备了高密度、高质量的CdS纳米带。通过扫描电子显微镜、透射电子显微镜、X射线衍射和光致发光光谱对纳米带进行了表征。CdS纳米带被发现是高相纯度和低缺陷密度的单晶。激光在CdS纳米带中观察到光泵浦。CdS纳米带的生长过程符合气-液-固机理。
High-density and high-quality CdS nanoribbons were synthesized by a thermal evaporation process. The nanoribbons were characterized by scanning electron microscopy, transmission electron microscopy, x-ray diffraction, and photoluminescence spectroscopy. CdS nanoribbons were found to be single crystals of high phase purity and low defect density. Lasing was observed in the CdS nanoribbons upon optical pumping. The growth of CdS nanoribbons was explained by the vapor–liquid–solid mechanism.
