WebExcitation range and maximum. An excited fluorophore molecule emits lower-energy light than the light it absorbs. Therefore, there is always a shift along the spectrum between the color of the light absorbed by the fluorophore during excitation, and the color emitted. A fluorescent dye absorbs light over a range of wavelengths—and every dye ...
