摘要：

A novel solventothermal route to group II-VI nanocrystalline CdE (E = S Se, Te) semiconductors has been successfully developed. The reaction can be expressed as solvent CdC2O4 + E [GRAPHICS] CdE + 2CO(2)up arrow. As-prepared CdE powders in polyamines such as ethylenediamine, diethylenetriamine, and triethylenetetraamine display rodlike morphology with diameters of 20-50 nm and lengths up to several microns. The morphology of CdE powders in the present method can be controlled by choosing different solvents. The CdS nanorods synthesized in polyamines display different optical properties from the disklike CdS particles synthesized in pyridine.
