采用简单的热蒸发方法生长了大尺寸、超长的CdS纳米线。纳米线的直径为100-500 nm，长度可达1 mm。提出了Sn催化的气-液-固机理来解释生长过程。研究了单纳米线和多纳米线互连结构的光波导行为，结果表明CdS纳米线是一种良好的光波导材料，在纳米光子器件或系统中具有潜在的应用前景。(C)2010爱思唯尔有限公司版权所有。
Large-scale, ultralong CdS nanowires (NWs) were grown by a simple thermal evaporation process. The NWs have diameter of 100-500 nm and lengths up to 1 mm. A Sn-catalytic vapor-liquid-solid mechanism is proposed to explain the growth process. The optical waveguide behavior of both individual NW and multi-NWs interconnected structures have been investigated, which indicates that the as-prepared CdS NWs are good optical waveguide material and may find potential applications in nano-photonic devices or systems.
