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.
