透明导电ZnO薄膜的电化学制备及性能研究
Transparent Conductive Properties of ZnO Thin Films Prepared by Electrochemical Deposition
摘要
Abstract
By using the constant-current electrochemical method, nanostructure ZnO was deposited on the modified ITO substrate, the relationship between Zn(NO3)2·6H2O concentration and the morphology , the crystalline phases, morphology and thickness, sheet resistances, transmittance, the oxidation and reduction potential were researched by XRD, FE-SEM, RTS-8, UV-Vis, Cyclic Voltammetry. The results indicated that one-dimensional (1D) nanopillars were prepared by low concentration of electrolyte, whereas two-dimensional (2D) nanodisks with compact hexagonal were obtainted by high concention of electrolyte. UV-Vis spectroscopy revealed that the transmittance of ZnO nanopillars and nanodisks were more than 85% at the range of 400 ~ 900 nm, RTS-8 analysis indicated that sheet resistances of ZnO thin films are about 14.5 Ω/□, Cyclic Voltammetry analysis indicated significant differences of the potentials of oxidation and reduction between two kinds of morphology, whose ZnO nanopillars were -0.54 V(VS. SCE)and ZnO nanodisks were -0.72 V(vs. SCE), respectively. The results revealed that ZnO thin films with nanodisks had better chemical stability.关键词
