Abstract Copper sulfide (CuS), copper-deficient p-type semiconductor material, has been widely utilized due to its unique optical properties, low toxicity, and cost-effectiveness. Although many studies have been conducted on synthesizing CuS nanoparticles, harsh synthetic conditions and low yield must be solved. This study presents a new methodology that can synthesize CuS nanoparticles in large quantities at room temperature and pressure using high-concentration Cu complex ion precursors.
