interest in the field of optoelectronic devices due to their outstanding properties, such as
high photoluminescence quantum yield (PLQY) and size-and composition-controlled
tunable emission wavelengths. However, the toxicity of lead (Pb) element in the lead
perovskite NCs is the bottleneck for the commercial application of perovskite NCs. Herein,
we report a facile ligand-assisted synthesis to achieve lead-free Cs3Cu2Cl5 NCs with a high …
