利用简单的化学气相沉积法,成功地合成了高结晶度的Cd1-xZnxS纳米带和纳米板。使用X射线衍射仪、扫描电镜、透射电镜和选区电子衍射,对样品的形貌、晶体结构和组成成分进行了表征。研究发现,通过适当调节沉积位置,可以实现对样品形貌的控制合成。在合成过程中,气-固(VS)生长占据主导地位。光致发光研究发现,合成的纳米带和纳米板非常适合于构建纳米级别的光电器件,例如激光二极管,光子探测器。
Cd1-xZnxS nanobelts with high crystallinity and nano-plates were successfully synthesized by simple chemical vapor deposition. The morphology, crystal structure and composition of the samples were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy and selected area electron diffraction. The study found that by properly adjusting the deposition position, the morphology of the sample can be controlled and synthesized. During the synthesis, gas-solid (VS) growth dominates. Photoluminescence studies have found that the synthesized nanoribbons and nanoplates are well suited for the fabrication of nanoscale optoelectronic devices such as laser diodes and photon detectors.
