Nanopowder Metal Oxide for Photoluminescent Gas Sensing

Gas sensing properties of metal oxide nanopowders (ZnO, TiO(2), WO(3), SnO(2)) with average diameters of 40–60 nm were analyzed by room-temperature photoluminescence spectroscopy. The influence of gas environment (O(2), N(2), H(2), CO, CO(2)) on the emission intensity was investigated for metal oxid...

description Gas sensing properties of metal oxide nanopowders (ZnO, TiO(2), WO(3), SnO(2)) with average diameters of 40–60 nm were analyzed by room-temperature photoluminescence spectroscopy. The influence of gas environment (O(2), N(2), H(2), CO, CO(2)) on the emission intensity was investigated for metal oxide nanopowders with surface doped by impurities (Pt, Ag, Au, Sn, Ni or Cu). Established physicochemical regularities of modification of surface electronic states of initial and doped nanopowders during gas adsorption. The nature of metal oxide nanopowder gas-sensing properties (adsorption capacity, sensitivity, selectivity) has been established and the design and optimal materials for the construction of the multi-component sensing matrix have been selected.
