The synthetic nano-particles were measured by XRD, TEM and IR. The results showed that different synthetic methods affected the size (from 20nm to 50nm or so) and shape (regular ball shape, irregular ball shape and bar shape) of CuS nano-particles. These methods were available for simple synthesis technology, less cost and easily industrial production.展开更多
