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.

AbstractA theoretical analysis of the mechanism of generation of singlet oxygen in the presence of photoexcited nanoporous silicon is presented. It is demonstrated that the mechanism of generation of singlet oxygen is based on nonradiative energy transfer from nanoporous silicon to an oxygen molecule by the exchange mechanism. An analytical expression of the probability of energy transfer from nanoporous silicon to an oxygen molecule is obtained, and a numerical estimate of this process is given. The numerical estimation is of the order of 10^3–10^4 s^–1, a value that agrees rather well with the experiment.

Splitting Effect

The splitting effect that is observed in microdiffraction pat-terns of small metallic particles in the size range 50-500 Å can be understood using the dynamical theory of electron diffraction for the case of a crystal containing a finite wedge. For the experimental data we refer to part I of this work in these proceedings.
