Laser-induced fluorescence (LIF) or laser-stimulated fluorescence (LSF) is a spectroscopic method in which an atom or molecule is excited to a higher energy level by the absorption of laser light followed by spontaneous emission of light. What is a Fluorescence Microscope? Some minerals have an interesting physical property known as "fluorescence."

Fluorescein isothiocyanate (FITC), for example, will absorb light from 400-530 nm but absorbs most efficiently at its peak or excitation maximum of 490 nm wavelength. 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 photon energy, than the absorbed radiation.A perceptible example of fluorescence occurs when the absorbed radiation is in the ultraviolet The peak excitation wavelength for L-tyrosine was determined in a similar fashion as Fluorescence is the property of some atoms and molecules to absorb light at a particular wavelength and to subsequently emit light of longer wavelength after a brief interval, termed the fluorescence lifetime. wavelength of the fluorescent light.

In fluorescence spectroscopy, both excitation and emission wavelengths are characteristic. Excitationemission matrix (EEM) fluorescence spectroscopy has been widely used to characterize dissolved organic matter (DOM) in water and soil. The implication of the wavelength effects combined with the fact that the energy of the evanescent wave decreases exponentially in the z direction, is that highly specific fluorescent excitation can be induced in a very thin optical section, typically less than 100 nanometers in thickness.
