Abstract
Peculiarities of photoluminescent properties of metal oxide nanopowders (ZnO, TiO2, SnO2, WO3) including laser-modified and surface doped by impurities (Au, Ag, Pt, Ni, Cu, Sn), in gases (О2, N2, H2, CO, CO2) were studied. Nature of sensor properties of the metal oxide nanopowders (adsorption capacity, speed, sensitivity, selectivity) were established; the best structure and materials for the development of a multicomponent recording matrix were selected. The efficiency of the constructed sensor system for the gases’ and their mixtures detection and analysis was found. The developed gas sensor system allows detecting not only separate gas components, but their mixture with high sensitivity and selectivity, providing the possibility to reach the modern level of the formation of gas sensor systems with improved performance.
