Lifetime fluorescence is a subset of fluorescence spectroscopy in which the time between excitation and relaxation is measured, rather than just the intensity of the emitted energy. The technique is used primarily in biological applications, but has a number of other uses as well. Lifetime fluorescence is a well-established niche market.
