That part can be explained by florescence. Some of the absorbed light of
shorter wave length get re-emitted as longer wave length.
One blue photon is absorbed and re-emitted as 2 red photons or a red and
an infra red photon.
Notice that the excess tend to be in the dark red region of the
spectrum, almost infra red.
