Light changing coatings using photoactive nanomaterials to boost plant growth
School of Engineering
Plants are known to require certain wavelengths of light for growth. The idea is to convert the light that the plants do not need into useful light: red (620-740 nm) and blue (450-495 nm). This should enable the plants to grow more effectively and rapidly. Final year project students are involved in developing a special coating using nanoparticles which can shift the unusable wavelengths of the sunlight to the red and blue wavelengths. Average plant growth enhancements was observed for 40 % increase in leaf area and 20% increase in chlorophyll in 95 % of the plants grown during the project.
