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.

不同盐的乙醇溶液喷涂的氧化锌薄膜的电反应和微观结构发展

使用硝酸锌、氯化锌和醋酸锌的乙醇溶液在玻璃基底上通过喷雾热解法制备了氧化锌薄膜。在用这三种盐制备的薄膜中观察到了不同的微观结构，与用相同盐的水溶液制备的薄膜相比差异显著。聚乙二醇也被用作孔隙生成剂，以改变致密薄膜的微观结构，增加孔隙度。在 365 纳米紫外线和氢气存在下，分别评估了薄膜在室温下的电反应。使用不同锌盐在氧化锌薄膜中形成的微观结构与测得的电特性相关。

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.
