Abstract
The present invention has the objective to increase the light output yield of a light conversion foil in comparison to the impacting light. There is proposed to realize the following effects in the various layers of a conversion foil, individually or in combination, namely the isolation of the conversion layer () from the support () by a, preferably microporous and mesoporous, interlayer (), and the incorporation of scattering centers () either into this interlayer, or into the conversion layer, or into both.
