Fluorescence is a photoluminescence process which consists of the emission of photons along the de-excitation of molecular species from the excited state S 1 to the ground state S 0. The loss of energy by molecular species in the excited state may occur through radiative processes (i.e., with photon emission) or via nonradiative (i.e., without photon emission) de-excitation mechanisms, as schematized in Fig. 1.
