Abstract: Copper nanoclusters (CuNCs) were synthesized using glutathione and cysteine as ligands, respectively. According to the photoluminescence mechanisms of CuNCs, we investigated the effects of various factors on their photoluminescence properties, including ligands, radicals, pH, solvents, and temperature. Based on these findings, a Copper Nanoclusters Photofluorescence Kit was successfully developed. The kit is portable, safe, and applicable across a broad range of public science education scenarios, effectively engaging the public’s interest in nanomaterials and actively enhancing their understanding of the charm of chemistry.
