中文摘要	nanostructured copper sulfides have attracted much attention due to their unique electronic and optical properties and potential applications in many areas. this article presents a high-temperature precursor-injection method to synthesize covellite copper sulfide (cus) nanoplates by using oleylamine as capping ligands. the synthesized cus nanoplates were found to be self-assembled into face-to-face one-dimensional columnar arrays with the longest column of 0.75 mu m. further studies showed that the reaction temperature has strong effects on the size, size distribution and the self-assembly behaviors of the cus nanoplates. the self-assembly behaviors were found to be tuned by the reaction temperature. in the range of 140-180 degrees c, the face-to-face self-assembly is formed over the entire substrate, whereas only edge-to-edge arrangements were observed at the reaction temperature of 200 degrees c. as the temperature further increases, the product exhibits a mixture of large and small nanocrystals and there is not any presence of self-assembly. the present study highlights the size-controlled synthesis of copper sulfide nanoplates and their self-assembly behaviors dependent on reaction temperature.
