โœฆ Synopsis


Well-de5ned ternary CuInS 2 nanorods 20+25 nm in diameter and 400+450 nm in length were synthesized by the reaction of CuCl 2 , In, CS 2 , and NaOH at temperature as low as 1803C for 15 h when water was used as the solvent. The products were characterized by X-ray di4raction, transmission electron microscopy, selected area electron di4raction, X-ray photoelectron spectroscopy, and UV+vis absorption spectroscopy techniques. Experimental results indicate that reaction temperature is an important factor in this approach and liquid indium plays an important role in the formation of CuInS 2 nanorods. Finally, a solution+liquid+solid mechanism was proposed for the nanorod growth.
