The fundamental regularities of optical, electronic and charge-transit processes in zinc, tin and ruthenium oxides have been revealed and the mechanisms of these interactions have been proposed. The common for these oxides is the possibility of their application to solve environmental problems. Such use is associated with surface phenomena in the material, which requires maximum unfolding of its surface. Methods have been developed to enhance the surface expansion of thin films in the case of using the specified oxides in this form. It has been demonstrated that the best surface disclosure can be achieved by converting the oxide into an ensemble of nanoparticles in a porous matrix. The types of sparse matrices were considered and the most suitable of them was chosen. It was found that zinc and tin oxides can be used as an active element for resistive (in the form of thin films) ammonia donors. The ability of thin nanostructured zinc oxide films immobilized by virus antibodies to change the nature of photoluminescence upon interaction with the proteins of these viruses was revealed and explained. This makes it possible to use the studied films as immunobiosensors. It was found that ruthenium dioxide does not luminesce in any form, but has catalytic properties. The latter is explained by the electronic structure of ruthenium atoms, due to which they are able to stimulate the redistribution of the charge density inside the molecules of aromatic pollutants, which is necessary for their transformation into insoluble oxides. It was demonstrated the possibility of recording the purification process completion due to the disappearance of the system luminescence, since aromatic pollutants luminesce well, unlike their oxides and the catalyst which do not at all.
