COLLEGE BOTANY: SEM - VI, PAPER - DSE4T: ANALYTICAL TECHNIQUES IN PLANT SCIENCES, UNIT - 1: FLUORESCENCE MICROSCOPY What is fluorescence microscopy? A fluorescence microscope is an optical microscope A . fluorescence microscope.  is an optical microscope that uses fluorescence and phosphorescence instead of, or in addition to, reflection and absorption to . study . organic . or inorganic substances. Introduction. Fluorescence is a kind of a luminescence, which is the emission of photons from electronically excited states. Fluorescence occurs when the electron is transferred from a lower energy state into an "excited" higher energy state. . Several of pathways for loss of electronic excitation shown in Fig. as a emission of light as luminescence. The individual luminescence phenomena are named according to the mode of excitation of the energy-rich species. Emission from species excited by absorption of radiation is referred to fluorescence or phosphorescence Emission following excitation by chemical reaction (of natural or changed species) is . It is a phenomenon of emission of radiation when the molecules are exited by radiation at certain wavelength.. FLUORIMETRY:-. It is measurement of fluorescence intensity at a particular wavelength wit the help of a filter fluorimeter or a spectrofluorimeter.. -based drugs. Ye, Yu, . Stepanenko. 1,. *, . R.O.
