Natural and Artificial Light-Harvesting Systems Utilizing the Functions of Carotenoids
Publication date: Available online 5 August 2015 Source:Journal of Photochemistry and Photobiology C: Photochemistry Reviews Author(s): Hideki Hashimoto, Yuko Sugai, Chiasa Uragami, Alastair T. Gardiner, Richard J. Cogdell Carotenoids are essential pigments in natural photosynthesis. They absorb in the blue-green region of the solar spectrum and transfer the absorbed energy to (bacterio-)chlorophylls, and so expand the wavelength range of light that is able to drive photosynthesis. This process is an example of singlet–singlet energy transfer and so carotenoids serve to enhance the overall efficiency of pho...
