Abstract:An interaction of molecular oxygen and p‐Si nanocrystallites in HF–ethanolic solution with simultaneous illumination has been investigated. It is shown that after such treatment with white‐light exposure the photoluminescence from nanocrystallites enhances substantially caused by photogenerated singlet forms of molecular oxygen. In the case of monochromatic illumination with photon energy in the range 2.5–0.95 eV dependence of photoluminescence intensity after the treatment on photon energy used shows resonant… Show more
