Effect of the Relative Spatial Arrangement of a Metal Nanoshell and an LH2 Complex of Photosynthetic Bacteria on the Optical Properties of the Hybrid Light-Harvesting Structure

Section: Nanosystems
Original Author's Text: Ukrainian

Abstract: The influence of the relative spatial arrangement of a silver nanoshell and a peripheral LH2 complex of photosynthetic bacteria on the light absorption enhancement by the hybrid lightharvesting complex has been studied theoretically. The enhancement of light absorption in the interval of the B850 exciton band arises owing to the strong interaction between excitons in the LH2 ring and surface plasmons in the nanoshell. The range of hybrid structure parameters has been determined, at which the enhancement of the photosynthesis process efficiency in the presence of a silver nanoshell is possible.

Key words: light-harvesting complex, nanoparticle, exciton, plasmon, photosynthetic bacterium.
