Hybride C-60 - silica based materials have been synthesized by microemulsion assisted sol gel procedure. In this respect, the versatility of these soft nanotechnologies has been exploited in order to obtain various type of nanostructures, such as C-60 - silica coated nanoparticles and C-60 - silica based composites The size, morphology and distribution of fullerene within the silica matrix, in liquid/solid phase, have been evaluated by adequate techniques: DLS, HR-TEM/SAED, XRD, BET. The size effect, photostability and semiconducting properties (band gap values) of the materials obtained have been quantified by means UV-VIS-NIR diffuse reflectance spectra. By corroborating these physico - chemical characteristics it can be concluded that these C-60 - silica based hybride nanomaterials are promising in applications as optical devices, light-induced charge separation, semiconductors, chemical sensors, catalysis and in the medical field.
