Phosphorescence and fluorescence are to be described and the differences between phosphorescence and fluorescence are to be discussed. Concept introduction: Electromagnetic radiation with a certain wavelength is called light. The process in which a fluid or a substance is dissolved or absorbed in bulk is called absorption. Excitation of electrons is the transfer of a bound electron from a lower energy state to a higher energy state (excited state) due to absorption of energy. The process in which an electron escapes or is radiated from a metal surface is called electron emission.
