利用化学气相沉积方法成功合成了CdS掺Cu的一维纳米结构,揭示了该掺杂纳米结构特殊的生长机制,发现了该结构新颖的光子学性质.实验表明,通过控制实验条件可以实现CdS中Cu离子掺杂,并可获得高质量的一维纳米结构.由于掺杂离子的影响,纳米结构在不同强度的光激发时表现出不同线形的发光光谱,掺杂浓度对发光峰的位置和相对强度有比较明显的影响,但对光谱线形影响不大.所得结果将有助于拓展CdS纳米结构在纳米光子学领域中的应用.
CdS-doped one-dimensional nanostructures were successfully synthesized by chemical vapor deposition method, revealing the special growth mechanism of the doped nanostructures and discovering the novel photonic properties of the structure. Experiments show that CdS can be achieved by controlling the experimental conditions Cu ion doping and high-quality one-dimensional nanostructures.Due to the influence of doping ions, nanostructures show different linear emission spectra under different intensity of photo-excitation, the position and relative position of the doping concentration on the luminescence peak The intensity has a more obvious effect, but it has little effect on the spectral line shape.The results will help to expand the application of CdS nanostructures in the field of nanophotonics.
