Fluorescence reading
WebThe basic fluorescence properties of a fluorophore—excitation and emission—are often presented in the form of line graphs. These curves describe the likelihood that excitation and emission will occur as a function of wavelength and provide important information about the expected behavior of the irradiated fluorophore.

WebFluorescence is the property of some atoms and molecules to absorb light at a particular wavelength (the excitation: Ex) followed by a short-lived emission (Em) of light at a longer wavelength (Figure 2). The distance between the excitation and emission peaks is known as the Stokes shift and is fluorophore dependent (Figure 1). WebFluorescence definition, the emission of radiation, especially of visible light, by a substance during exposure to external radiation, as light or x-rays. See more.

Fluorescence spectroscopy (also known as fluorimetry or spectrofluorometry) is a type of electromagnetic spectroscopy that analyzes fluorescence from a sample. It involves using a beam of light, usually ultraviolet light, that excites the electrons in molecules of certain compounds and causes them to emit light; typically, but not necessarily, visible light.
