This phenomenon is Fluorescence instantaneous i.e start emitting radiation immediately after the absorption and stops when incident light is cut off. Fluorescent substances emit maximum radiation with in 10- 10 to 10-8sec of absorption. This is also called delayed fluorescence
WebDec 18, 2024 · Fluorimetry is one of the widely used tools in detecting and analyzing different phytoplankton species by measuring the fluorescence signals emitted from the photopigments [ 5 ]. Previously, we have reported a fluorometer system in [ 6, 7] based on controlled samples.
WebNov 24, 2024 · Fluorometry is an analytical method to measure the emitted fluorescent light. It is the emission of electromagnetic radiation when a specie absorbs exciting radiation from any outside source. The intensity of emitted light will be directly proportional to the concentration of the excited species.
