Abstract Delayed light emission (DLE) from aggregated chlorophyll is used to probe energy transfer between aggre­ gated chlorophyll and β-carotene. Preilluminated β-carotene when injected into a dark chamber containing aggregated chlorophyll, induces DLE from aggregated chlorophyll. If the dark chamber contains only monomeric chlorophyll, there is no DLE. The intensity of DLE is dependent on the time of illumination of β-carotene. The decay of energy stored by the carotene is not a first order process. The first half life is about 2 min, the next about 10 min
