dc.description.abstractThe paper presents the results of studies of the Technological Stages of Obtaining High-Silica Powders Containing Copper Ions by the Sol-Gel Method. It has been shown that metal nanoparticles in a xerogel matrix are nanostructured objects with high chemical and “penetrating” activity with respect to the occurrence of thermally stimulated surface reactions, while the SiO2 matrix retains an amorphous system, whereas CuO and Cu° form a monoclinic crystalline syngony. Based on the results of SEM data, it was suggested that the reduced metal is sorbed into the globular structure of the xerogel, forming a thin composite layer on the SiO2 surface. No pronounced formation of separately localized Cu° micro- and nanoparticles was found. From the obtained high-silica SiO2:CuO and SiO2:Cuº powders, targets were formed for the deposition of thin films by electron-beam or magnetron sputtering with a diameter of up to 80 mm.ru_RU
