Organic photostimulated luminescence associated with persistent spin-correlated radical pairs

Abstract Photostimulated luminescence allows energy or data to be stored and released using electromagnetic waves as both the input output, has attracted considerable interest in fields of biomedical information technologies. However, this phenomenon is mostly limited solid inorganic materials. Here, we report photostimulated from purely organic blend films, composed electron donor, acceptor, trap/emitter molecules. Charges films are accumulated radical ions by ultraviolet light irradiation then extracted near-infrared irradiation. Even after storage dark for one week they produce visible with good repeatability, color tunability, responsive weak external magnetic fields. These findings might broadly impact existing applications provide new prospects innovative flexible devices.
