Organic-Inorganic Nanosystem Based on Fullerene Embedded in Porous Silicon Matrix

The structure and luminescent properties of a hybrid system based on fullerene C60 embedded in a porous silicon matrix have been studied. The investigation of the surface topology of a por-Si-C60 nanostructured layer by AFM shows clearly the incorporation of C60 nanocrystals inside pores of silicone. According to FTIR spectroscopy, a covalent interaction between the surface of a fullerene cluster and porous silicon takes place. This has influence on the luminescent properties of porous silicon, which is of a special interest for cathode luminescence spectra with the appearance of an additional band at E = 3.2−3.4 eV. A possible mechanism of such an effect is discussed.
