Abstract (en)

[origin: WO2019025742A1] The present invention relates to a material for optically doping a polymer substrate, characterised in that it is formed by poly(methyl methacrylate) and at least two organic photoluminescent materials with a concentration of photoluminescent materials close to the solubility limit of the photoluminescent materials in the MMA between 0.1% and 2% by weight. The invention also relates to a film doped with such a material, as well as a greenhouse covering, a photovoltaic panel implementing such a material, and a method for preparing such a material.
