UV-to-red light converting films accelerate plant growth

An interdisciplinary team from Hokkaido University’s Engineering and Agriculture departments and the Institute for Chemical Reaction Design and Discovery (WPI-ICReDD) has developed a europium-based thin-film coating that they demonstrated accelerates both vegetal plant and tree growth. This technology can improve plant production speed and has the potential to help address global food supply issues. Plants …
