The fluorescence emission, the absorption, and the fluorescence excitation spectra of zeaxanthin (Z) and violaxanthin (V) aggregates formed in a water-ethanol solvent system have been measured. Fluorescence quantum yield for zeaxanthin and violaxanthin are: &Z)=4.3~10-" and &V)=1.7~ IO-'. The fluore
