Optical Properties and Synthesis of Copper Sulfide Nanorods by Solid-state Reaction at Low Heating Temperature

Abstract

Abstract: Well-dispersed copper acetamide sulfide nanorods were prepared by means of the solid-state reaction of copper acetate and thioacetamide in the presence of surfactant PEG-400 at a low heating temperature. The powder X-ray diffraction pattern and EDX indicated that the product was pure hexagonal phase copper sulfide nanorods. The morphology of the nanorods was characterized by transmission electron microscopy(TEM) and scanning electron microscopy(SEM). The diameter and length of CuS nanorods obtained are 80-100 nm and 200-500 nm, respectively. And the maximum peak positions of absorption spectrum and excited spectrum of CuS nanorods were observed to shift towards higher wave number compared with those of the bulk CuS. The results clearly show the fine optical properties of CuS nanorods.

Key words: Nanorod, Copper sulfide, Solid-state reaction, Optical property
