Luminescent greenhouse glazing structures are described wherein the glazing structures comprise: a glass pane for a greenhouse; and, one or more Eu2+ doped amorphous inorganic luminescent thin film layers provided over the glass pane, wherein the one or more Eu2+ doped amorphous inorganic luminescent layers comprise or consist essentially of the elements Al and/or Si and the elements O and/or N; and, wherein the Si concentration is selected between 0 and 45 at.%, the Al concentration between 0 and 50 at.%, the O concentration between 0 and 70 at.%, the N concentration between 0 and 60 at.% and the Eu2+ between 0.01 and 30 at.%. L'invention concerne des structures luminescentes de vitrage de serre, les structures de vitrage comprenant : une vitre pour une serre ; et une ou plusieurs couches d'un film mince luminescent inorganique amorphe dopé à Eu2+, disposées sur la vitre, la ou les couches luminescentes inorganiques amorphes dopées à Eu2+ comprenant, ou en étant constituées, essentiellement les éléments Al et/ou Si et les éléments O et/ou N ; et la concentration de Si étant choisie entre 0 et 45 % en atomes, la concentration d'Al entre 0 et 50 % en atomes, la concentration d'O entre 0 et 70 % en atomes, la concentration de N entre 0 et 60 % en atomes, et celle de Eu2+ entre 0,01 et 30 % en atomes.
