Light‐Induced Stark Effect and Reversible Photoluminescence Quenching in Inorganic Perovskite Nanocrystals

Inorganic perovskite nanocrystals (NCs) have demonstrated a number of unique optical and electronic properties for optoelectronic applications. However, the physical these nanostructures, such as dynamics charge carriers on different timescales their effect recombination carriers, are not yet fully understood. This work reports slow (>1 s) reversible quenching NC photoluminescence due to light-induced Stark involving defects surface NCs redistribution photoexcited onto surface. phenomenon can influence operation devices based NCs, including hybrid photosensors graphene decorated with inorganic revealing prospects limitations.
