The use of matrices of different types makes it possible to prepare nanocomposites differing in the degree of ordering,the size and shape of structural units,their spatial distribution,and the type of contact between them.Porous glasses with controlled characteristics of pores can be used as matrices for nanocomposites.This provides a means for determining the basic parameters and the main properties of nanoclusters as a function of the size of their structural units.It is shown that the structural parameters of porous glasses can be controlled by varying the conditions of thermal and chemical treatments of the initial glasses.
