Fluorescence is the phenomenon whereby some products or substances emit energy in the form of light when irradiated with ultraviolet light. Fluorescence should not be confused with phosphorescence. In phosphorescence, the particles store the energy and then radiate it after the ultraviolet light irradiation has been completed.<\/p>\n\n\n\n

To really understand the fluorescence process, it is necessary to remember the atomic orbital and molecular orbital model. According to the uncertainty principle, an electron can be found within a certain energy level range, in a lower or higher level. There are low-energy and high-energy orbitals. Electrons by default prefer to occupy low-energy orbitals, but can transiently occupy higher energy levels. <\/p>\n\n\n\n

These orbital jumps are achieved in certain substances by irradiating them with energy. These jumps are known as electronic transitions. Each type of atom has very characteristic absorption lines and emission lines.<\/p>\n\n\n\n
