Аннотация:Radiation between 400 and 700 nm, used for oxygenic photosynthesis by cyanobacteria,
algae and plants, represents only 44% of total solar energy while the range above 700 nm
comprises 52%. An ability to use near infrared (NIR, 700e1200 nm) radiation would greatly
improve the efficiency of photosynthesis, but NIR photons have too low energy to excite
the photosystems of oxygenic photosynthesis. Here we show that a mechanism called
photon up-conversion can turn NIR radiation into an energy source for photosynthesis. In
the future, it may be possible to up-convert the NIR part of the solar energy flux to visible
light for use in photo-induced biohydrogen production by oxygenic photosynthesis.
