 Fluorescence spectroscopy

Spectroscopy measuring emitted light following excitation. Emission peak position and intensity can report changes of speciation, but concentration, excitation absorption and photochemical loss also influence the signal.

Fluorescence spectroscopy is an analytical technique used to measure the fluorescence emitted by a substance after it has absorbed light or other electromagnetic radiation. This technique is based on the principle of fluorescence, where certain molecules (fluorophores) absorb light at a specific wavelength and subsequently emit light at a longer wavelength.
