A magical world as sumptuous as it is unexpected!
Fluorescence is a process in which an atom absorbs energy, usually light at a certain wavelength, and immediately re-emits light at another wavelength. The molecules that fluoresce are mostly cyclic and rigid. They are called “fluorophores” or “fluorochromes”. These are characterized by several parameters such as: the wavelengths of their excitation and emission peaks; the lifetime of their excited state; the efficiency of their fluorescence (i.e. the number of photons emitted compared to the number of photons absorbed).
