WebIt is not the emission of an electron that produces a photon. A photon is produced when an electron releases energy by moving to a lower energy level within the atom. When the atom absorbs energy, it re-emits it in a random direction, almost instantaneously. The exact time delay is random, but always so fast that it seems pretty much instantaneous. WebOne initial problem with the use of GFP was the excitation and emission spectra of the wild type protein for fluorescence microscopy. Wild type GFP has two excitation peaks, a major one at 395 nm (in the long UV range) and a smaller one at 475 nm (blue) and its emission peak at 509 nm (green).
