January 04, 2024. A fluorophore is an organic molecule with the ability to absorb light at a particular wavelength and then emit it at a higher wavelength. To achieve this, photons of light from an excitation source are absorbed by the fluorophore’s electrons, raising their energy level and causing them to move to an excited state.
