AB  - Cu(I)-based low-dimensional metal halides have received significant recognition attributable to their intriguing optoelectronic properties, which instigate the emergence of self-trapped excitons (STEs) accompanied by intense broadband emissions. However, fundamental crystal structural origin of such STE is still elusive. Herein, we have synthesized Cu(I)-based mixed halide, Cs5Cu3Cl6I2 nanoplates (NPs) using room temperature ligand-assisted reprecipitation method, which showed an intense blue emission with broad line-width, large Stokes shift, long photoluminescence lifetime, high photoluminescence quantum yield (PLQY) of ∼75
