Direct vertical deposition method of zinc oxide nanometer rod array on titanium dioxide film

Abstract

The invention discloses a direct vertical deposition method of a zinc oxide nanometer rod array on a titanium dioxide film, wherein the zinc oxide is an important inorganic semiconductor function material and arouses wide public concern due to the unique performances of catalysis, electricity, optics and photochemistry, and the like. Persons are interested in the control synthesis of one-dimensional zinc oxide due to the remarkable laser behavior of the one-dimensional zinc oxide. The method comprises the steps of: preparing titanium dioxide sol under room temperature; preprocessing; adheringwith one layer of titanium dioxide sol on a preprocessed glass or an electric glass ITO by means of dipping and pulling; preprocessing titanium dioxide grains before drying and spinning; fixing a layer of titanium dioxide grains prepared by means of a sol-hydrothermal method on the substrate by means of spinning; drying; roasting to obtain the nanometer zinc oxide film; putting the zinc oxide film into a sealed water solution system of zinc salt and organic amine; reacting for 12-72 h under the reaction temperature of 45-90 DEG C; taking out; washing with secondary water; and drying. The invention relates to a nanometer material.

Description

Technical field: [0001] The invention relates to a direct vertical deposition method of a zinc oxide nanorod array on a titanium dioxide film. Background technique: [0002] ZnO is an important inorganic semiconductor functional material, which has attracted widespread attention due to its unique catalytic, electrical, optical and photochemical properties. The remarkable lasing behavior of 1D ZnO nanowire arrays has spurred interest in the controlled synthesis of 1D ZnO. In recent years, various chemical, electrochemical, and physical deposition techniques have been widely used to synthesize one-dimensional ZnO nanorods, nanotubes, and nanowire arrays. For example, the use of hydrothermal decomposition of zinc amine complexes, chemical vapor transfer (CVT), physical vapor deposition (PVD), metal organic chemical vapor deposition (MOCVD), pulsed laser deposition (PLD) and electrodeposition methods have been successful. Synthesis of one-dimensional ZnO nanorod arrays. It is...
