Metal halide perovskites (MHPs) have recently gained intensive interests since they have demonstrated exceptional optoelectronic properties with EQE values exceeding 29% in light emitting diodes. In particular, 0D perovskites, with their broad emissions enabled by self-trapped excitons hold potential for developing a single-material-phosphor for white LEDs. However, scalable and facile synthetic methods for 0D perovskites with high quality and purity remain to be developed. Mechanochemical synthesis (MCS) is a promising method that is simple, environmentally friendly, and scalable, making it a suitable tool for synthesizing 0D perovskites. Here, representative Cs-Cu-I 0D perovskites were synthesized using ball milling and their intermediate phases were studied for elucidating structural-optical properties. The results of this study highlight the potential of MCS as a method for synthesizing 0D perovskites and investigating their structural origins of photophysical properties.
