In particular, we significantly lowered (<10%) size dispersion of nanoparticles size, which is one of the important factors for creating structures such as "quantum solid" with ordered arrays of quantum points or nanoparticles of noble metals in these media. We have got the results of the progress of electronic and excitonic processes in such structures, including established significant deviation of energy carriers from quadratic law in quantum dots II - VI semiconductors on substrates spherical SiO2 less than 300 nm, due to internal deformation of the lattice and form nanoparticles. The researches of cubic optical nonlinearity films, representing an array of structures: the core of SiO2, which are located on the surface of gold nanoparticles are conducted. We obtain the maximum coefficient of order nonlinear susceptibility on the field ? (3) ~ 10-7 esu.
