제목 Influence of applied bias for A-site and X-site ion exchange reaction dynamics in perovskite quantum dots​
초록 Due to the excellent photophysical properties of perovskite quantum dots, their introduction into solar driven chemistry and optoelectronic devices has been taken up as an attractive alternative. Despite the outstanding photophysical properties and successful application to photovoltaic devices, applied electrical field induced phenomena could induce various component change and time dependent variations in the perovskite quantum dots. In this study, we investigated the behavior of X-site halide and A-site cation exchange processes in between the perovskite quantum dots. Through in-situ photoluminescence spectroscopy under the applied bias, we figured out the role of applied bias and current to the exchange process to the exchange process. Through these studies, we were able to track the enhanced migration rate of ions in the batch solution could facilitate the ion interdot exchange reaction dynamics in between the perovskite quantum dots.​
