nanoparticles to oxygen dimers adsorbed on the nanoparticle surfaces
is studied as a function of temperature and magnetic field. Quenching
features in the nanoparticle photoluminescence spectrum arise from
energy transfer to the oxygen dimers with and without the emission of
Si TO(D) phonons and, also, with and without the vibrational excitation
of the dimers. The dependence of the quenching on magnetic field
shows that energy transfer is fast when a dimer is present, allowing an
estimate of the proportion of the nanoparticles with adsorbed dimers.
