Rapid Synthesis of Uniform CdSe Nanorods by a Microwave-Assisted Solvothermal Method in Ethylenediamine

A rapid microwave-assisted solvothermal method is reported for the synthesis of uniform CdSe nanorods in ethylenediamine (EDA) using CdCl₂ and elemental Se as reactants. The resultant nanorods have a diameter of approximately 10 nm and a length of approximately 300 nm. Our experiments show that the concentrations of EDA and CdCl₂ play important roles in product morphology. The well-dispersed CdSe nanorods with high aspect ratios were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), energy-dispersive X-ray (EDX), UV-vis absorption and photoluminescence (PL).
