Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. CachadLiknandeÖversätt den här sidanFluorescence is the result of a 3-stage process that occurs in certain molecules (e.g., polyaromatic hydrocarbons) called fluorophores. Fluorescence, a type of luminescence, occurs in gas, liquid or solid chemical systems.
