As described by Ryota Kabe, Chihaya Adachi, and Kazuya Jinnai in article number 1800365 , greenish‐blue to red and even warm white organic long‐persistent luminescence (OLPL) in organic luminescent materials is achieved by energy transfer from an exciplex in the OLPL matrix to the emitter dopants. The dopants improve the brightness and emission duration respectively through efficient radiative decay and the trapping of electrons.
