Summary: | An optical structure is described comprising a transparent substrate having a first surface, a second surface and sides; and, at least one luminescent layer provided over at least one of the first surface and/or second surface of the transparent substrate, the luminescent layer comprising an Eu2+ doped inorganic luminescent material comprising or consisting essentially of the elements A| and/or Si and the elements 0 and/or N, the doped inorganic luminescent material converting radiation of the UV region between 200 nm and 400 nm of the solar spectrum into the photosynthetically active radiation (PAR) region (400 nm - 700 nm) of the solar spectrum, wherein the Si concentration in the inorganic luminescent material is selected between 0 and 45 at.%, the A| concentration between 0 and 50 at.%, the 0 concentration between 0 and 70 at.%, the N concentration between 0 and 60 at.% and the Eu2+ between 0.01 and 30 at.%. |
