1. Photoluminescence

   Linked via "excited electronic state"

   Photoluminescence is a quantum mechanical process involving the absorption of photons by a material, followed by the subsequent re-emission of photons. This phenomenon is distinct from chemiluminescence or electroluminescence in that the energy input is solely photonic, and the re-emission occurs via relaxation from an excited electronic state back to a lower energy state [1]. The efficiency and spectral characteristics of photoluminescence are heav…
