In detail, the protonated 2,3-DAPN narrows the photon transition bandgap and finally triggers the one-photon and two-photon red fluorescence emission on CDs with the narrow luminescence band. Overview. The meaning of FLUORESCENCE is luminescence that is caused by the absorption of radiation at one wavelength followed by nearly immediate reradiation usually at a different wavelength and that ceases almost at once when the incident radiation stops; also : the radiation emitted. Aequorin is a calcium-activated photoprotein isolated from the hydrozoan Aequorea victoria. The fluorescence lifetime is an intrinsic characteristic of such a light emitting species and it indicates how long it will remain in an electronically excited state before returning to the ground state.
