Fluorescent lamp - Wikipedia
WebFluorescence in minerals occurs when a specimen is illuminated with specific wavelengths of light. Ultraviolet (UV) light, x-rays, and cathode rays are the typical types of light that trigger fluorescence. These types of light … Mechanism Fluorescence occurs when an excited molecule, atom, or nanostructure, relaxes to a lower energy state (usually the ground state) through emission of a photon without a change in electron spin. When the initial and final states have different multiplicity (spin), the phenomenon is termed … See more Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore a lower See more There are many natural compounds that exhibit fluorescence, and they have a number of applications. Some deep-sea animals, such as the greeneye, have fluorescent structures. See more Lighting The common fluorescent lamp relies on fluorescence. Inside the glass tube is a partial vacuum and a small amount of mercury. … See more An early observation of fluorescence was described in 1560 by Bernardino de Sahagún and in 1565 by Nicolás Monardes in the infusion known as lignum nephriticum ( See more There are several general rules that deal with fluorescence. Each of the following rules has exceptions but they are useful guidelines for … See more In August 2024 researchers reported the creation of the brightest fluorescent solid optical materials so far by enabling the transfer of … See more • Absorption-re-emission atomic line filters use the phenomenon of fluorescence to filter light extremely effectively. • Black light • Blacklight paint • Fiber photometry See more WebHow does fluorescence work?
