Singlet Oxygen Generation

A theoretical analysis of the mechanism of generation of singlet oxygen on the surface of photoexcited nanoporous silicon is presented. It is shown that the nonradiative energy transfer from nanoporous silicon to the oxygen molecule by the Dexter exchange mechanism is the basis for the mechanism of singlet oxygen generation. An analytical expression is obtained and a numerical estimate of the probability of energy transfer from nanoporous silicon to an oxygen molecule is given. It was shown that its numerical value ~ (10^3-10^4) s^{-1} agrees quite well with experiment.
