In this paper the features of photoluminescent properties in gases of ZnO nanopowders including lasermodified and surface-doped with impurities of noble metals (Au, Ag, Pt) have been studied. The influence of laser modified and surface doping of ZnO nanopowders with impurities of noble metals on the adsorption ability have been studied and it was found that(More)
Gas sensing properties of metal oxide nanopowders (ZnO, TiO2, WO3, SnO2) with average diameters of 40-60 nm were analyzed by room-temperature photoluminescence spectroscopy. The influence of gas environment (O2, N2, H2, CO, CO2) on the emission intensity was investigated for metal oxide nanopowders with surface doped by impurities (Pt, Ag, Au, Sn, Ni or(More)
