S. Y. Park and co‐workers demonstrate a novel and effective method to achieve highly efficient and color‐tuned (sky blue, green, and orange) exciplex emissions originating from the nanoscale interface between a polymeric donor—poly(N‐vinylcarbazole) (PVK)—and highly fluorescent nanostructured acceptors. An unprecedented approach to obtain a white‐emitting PVK film consisting of multiple exciplex emissions is also presented. Exciplex‐to‐exciton emission color switching due to the size evolution of the nanostructured acceptors is demonstrated and photophysically interpreted.
