Our study demonstrates that using the sol-gel method to form thin Me-SiO2 films with composite sols containing nanoparticles of hydrous silica and silver/gold metal or germanium dioxide makes it possible to vary metal particle size (on reductive heat treatment in hydrogen for GeO2) and size distribution, thus affecting optical characteristics of the films. Ge particles formed in GeO2-SiO2 system are smaller than those formed by reducing pure GeO2 films. Silica sols produced with sodium metasilicate were found to stabilize the silver and gold nanoparticles formed by chemical reduction.
