WebJan 30, 2024 · One direct transition is phosphorescence, where a radiative transition from an excited triplet state to a singlet ground state occurs.This is also a very slow, forbidden transition. Another possibility is delayed fluorescence, the transition back to the first excited singlet level, leading to the emitting transition to the ground electronic state. Webphosphorescence, emission of light from a substance exposed to radiation and persisting as an afterglow after the exciting radiation has been removed.
