Primary Processes. One molecule is excited into an electronically excited state by absorption of a photon, it can undergo a number of different primary processes.. Several of pathways for loss of electronic excitation shown in Fig. as a emission of light as luminescence. The individual luminescence phenomena are named according to the mode of excitation of the energy-rich species. Emission from species excited by absorption of radiation is referred to fluorescence or phosphorescence Emission following excitation by chemical reaction (of natural or changed species) is .
