采用水热法成功合成了Cd_(1-x)Mn)xS(x=0～0.05)纳米棒。采用扫描电镜、X射线衍射和Raman光谱表征Cd(1-x)Mn_xS的形貌和微结构,通过紫外光谱和荧光光谱表征其光学特性。结果表明:随着Mn~(2+)含量的增加,Cd_(1-x)Mn_xS纳米棒直径基本保持不变,但长度变短,形貌变得较杂乱,并且伴随产生颗粒。Mn~(2+)掺杂CdS纳米棒保持了六方CdS结构,Mn~(2+)在CdS纳米棒晶体中代替部分Cd~(2+)的位置构成置换式固溶体。Cd_(1-x)Mn_xS纳米棒的紫外吸收光谱和荧光光谱都随Mn~(2+)含量的增加而逐渐红移。

The Cd1-xMnxS (x=0-0.05) nanorods were successfully synthesized through the hydrothermal route. The morphology and microstructure of Cd1-xMnxS nanorods were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD) and Raman spectrometry. The optical properties of Cd1-xMnxS nanorods were investigated with ultraviolet-visible spectrophotometer (UV-Vis) absorption spectroscopy and photoluminescence (PL) emission spectroscopy. The results show that with the increase of Mn2+ in the samples, the morphology of products become disordered, accompanied with some nanoparticles. The di...
