AI Technical Summary
Technical Problem
Existing technologies have not effectively utilized non-photosynthetic light in sunlight, resulting in high costs and complex structures for promoting photosynthesis, making large-scale application difficult.
Method used
A photosynthesis-promoting sheet containing quantum dots and UV scattering agents is used to convert ultraviolet light in sunlight into blue and red photosynthetic-effective light. By configuring a UV scattering layer or a dichroic filter layer in the sheet, the photon flux density is increased.
Benefits of technology
It effectively increases the photon flux density of photosynthetic light, promotes the growth of crops and seaweed, reduces costs and simplifies the structure, and is suitable for large facilities and farms.

Abstract
The present invention aims to provide a photosynthesis promoting sheet which converts non-photosynthesis effective light such as ultraviolet light contained in sunlight into blue, red photosynthesis effective light, and can effectively increase the PPFD of the photosynthesis effective light at that time. The photosynthesis promoting sheet of the present invention is characterized in that it is a photosynthesis promoting sheet containing quantum dots, which has a quantum dot sheet having a first face which is a face irradiated with sunlight, and a second face on the opposite side of the first face which is a face from which the photosynthesis effective light is emitted, and which converts non-photosynthesis effective light into photosynthesis effective light, the quantum dot sheet containing a UV scattering agent.
