Composit materials - ncSi/SiOx and ncSi/Si2 were object of researches. For purpose achievement methods of a spectral photoluminescence, IR-spectroscopy, atomic-force microscopy and electronic microscopy with high resolution were used. Also technological conditions of reception of high-quality structures of nanocrystalline silicon have been defined. Communication between optical properties of nanosize crystals of silicon and is theoretically considered their sizes. The technique of definition of the sizes silicon nano-inclusions and their disorder on the basis of the analysis of spectra of a photoluminescence is developed. The technique of definition of structural characteristics of oxigen matrixes with built in nc-Si particles on the basis of IR-spectroscopy with the analysis of the form of a strip of absorption is developed. Correlation of data of electronic microscopy with results of the offered method is established. Certification of nanocrystalline silicon material of different type is spent. The carried out researches are accompanied by detailed patent search in questions which are considered in R and D project. Results of R and D project can be used in electronic industry at creation light of radiators and memory elements on base of nanosize silicon.
