Problems solved by technology

[0003] At present, the preparation of metal oxide semiconductor thin film materials such as iron oxide generally uses chemical vapor deposition method, sputtering method, sol-gel method, etc. These methods either require high equipment, and the control factors and conditions are complicated, resulting in high preparation costs. , or the prepared film is uneven, with many surface defects, poor light transmission, poor adhesion, etc.
As a commonly used preparation method for nanomaterials, the hydrothermal method has many advantages such as simple equipment and operation, rich and controllable morphology of the prepared materials, and stable properties. It is also used in the preparation of semiconductor metal oxide thin films. , but it did not solve the problems of uniformity and adhesion of the film

Abstract

The invention belongs to the technical filed of production of metal oxide semiconductor thin film materials, and concretely relates to a production method for depositing an iron oxide film on ITO conductive glass. The method is a simple production method for depositing the highly-transparent, uniform and stable iron oxide film on the ITO conductive glass. The iron oxide film is deposited on the ITO conductive glass through a hydrothermal technology by adopting soluble ferric salt and soluble oxalate as raw materials. The iron oxide film obtained in the invention is very uniform, has good light transmission performance and can be firmly combined with a substrate. The raw materials used in the invention are simple and cheap, and the raw materials and reaction raffinate have no pollution, so large scale industrial application does not generate the pollution problem. The method has the advantages of simple process operation, low requirements on a device, small energy consumption, and convenient and flexible control of the film.
