Abstract
Zinc oxide thin films were grown by spray-pyrolysis on glass substrates from ethanolic solutions of zinc nitrate, zinc chloride and zinc acetate. Different microstructures were observed in the films prepared with the three salts used, which showed significant differences with respect to films prepared from aqueous solutions of the same salts. Polyethyleneglycol was also used as a pore-generating agent in order to modify the microstructure of denser films increasing the degree of porosity. The electrical response of the films at room temperature was evaluated under 365 nm ultraviolet light, and in the presence of hydrogen, separately. The microstructures developed in ZnO films by using different zinc salts is correlated with the measured electrical properties.
期刊介绍：
Materials Research Bulletin is an international journal reporting high-impact research on processing-structure-property relationships in functional materials and nanomaterials with interesting electronic, magnetic, optical, thermal, mechanical or catalytic properties. Papers purely on thermodynamics or theoretical calculations (e.g., density functional theory) do not fall within the scope of the journal unless they also demonstrate a clear link to physical properties. Topics covered include functional materials (e.g., dielectrics, pyroelectrics, piezoelectrics, ferroelectrics, relaxors, thermoelectrics, etc.); electrochemistry and solid-state ionics (e.g., photovoltaics, batteries, sensors, and fuel cells); nanomaterials, graphene, and nanocomposites; luminescence and photocatalysis; crystal-structure and defect-structure analysis; novel electronics; non-crystalline solids; flexible electronics; protein-material interactions; and polymeric ion-exchange membranes.
