"WebJul 21, 2024 · Fluorescence is the spontaneous emission of a photon from a molecule or atom excited after absorption of light. If two fluorescent molecules (fluorophores) are very close together, a few nanometers apart, the energy can transfer directly from a "donor" to an "acceptor" fluorophore without an occurrence of light emission.
