A unidirectional light-extracting fluorescent film was designed for passive augmentation of photosynthesis and biomass production for leafy green lettuces grown indoors and in greenhouse facilities. The batch-processed films have a total light extraction efficiency of 89%, with a majority of the converted light directed towards lettuce crops. This film demonstrates application potential in greenhouses and other protected environments to increase crop production efficiency.
