Photosensitization of singlet oxygen generation in porous silicon (PSi) was investigated by simultaneous measurements of the photoluminescence (PL) of silicon nanocrystals (nc-Si) and the infrared emission of the 1Ξ”-state of oxygen molecules at 1270 nm (0.98 eV) at room temperature.

## Abstract We investigate the effect of oxygen molecule adsorption on the photoluminescence of porous silicon films of different porosity. The experimental results are explained by the photosensitization of singlet oxygen generation due to the energy transfer from excitons confined in Si nanocryst
