Abstract

We demonstrate ultralong room temperature phosphorescence from aggregates of an organic semiconductor by managing competing effects of aggregate-induced enhancement and quenching with a simple and scalable processing technique. These results are in contrast to conventional ultralong room temperature phosphors which employ single crystals or isolated molecules in a rigid host, thus imposing deleteriously strict molecular design and processing constraints. The photophysical mechanisms for aggregate-enhanced emission and quenching are discussed.
