Two-photon excitation microscopy takes advantage of this phenomenon to observe below the surface of living tissue.
Two-photon excitation microscopy takes advantage of this phenomenon to observe below the surface of living tissue. A dark-ground condenser makes it easier to observe this effect, and, similar to a superconducting magnet, this property is decreased by Förster resonance energy transfer in a process called quenching. The Franck-Condon principle describes absorption and this type of photoluminescence that immediately follows. Mercury vapor often is used in lamps that use this to convert ultraviolet light into visible light, and this is characterized by emitted photons with less energy than the absorbed photons. Name this process that stops quickly when incident radiation is stopped, often contrasted with phosphorescence.
