Working Principle 

It is a rapid and sensitive method for the characterization of molecular components present in a sample. Fluorescence spectroscopy is a type of electromagnetic spectroscopy which analyzes fluorescent molecules. It exploits the phenomenon of electron excitation upon collision with high energy particles like photons and other excited electrons. In the process of transition of polyatomic fluorescent molecules (fluorophores) from their higher energy level (excited state) to a ground state by lowering their energy level, photons are emitted. Fluorophores play the most important role in fluorescence spectroscopy. Fluorophores are the components in molecules that impart fluorescence. Mostly, fluorophores are the molecules which contain aromatic rings such as tyrosine, tryptophan, fluorescein, etc.
