Problems solved by technology

It can be seen from theoretical knowledge that because there are more intrinsic defects in ZnO, it has a high self-compensation effect on acceptor-doped ions, and the solid solubility of acceptor impurities is very low, making it difficult to achieve p-type transition, thus making semiconductor devices The p-n structure of ZnO, one of the core components, cannot be made, so the development and application of ZnO-based optoelectronic components are greatly restricted

Abstract

The invention relates to a preparation method for an Ag-Al co-doped p type ZnO film, which comprises the following steps: weighting a right amount of precursor zinc salt; taking an organic solvent with corresponding volume; dissolving the zinc salt into the organic solvent; adding diethanolameine as a stabilizing agent, wherein the mole weight of the diethanolameine is equal to the mole weight of zinc ions; adopting water-bath heating and continuously stirring; adding doped source aluminum nitrate and silver nitrate, and continuously stirring; taking out a solution, ageing into sol, coating a film on a substrate, and then pre-processing; and performing annealing treatment, thereby obtaining the required film. The preparation method is simple in process; the cost of equipment is low; the required raw materials are easily obtained; the uniformity of the film is excellent; the preparation method can be applied to industrialized production; and the application prospect is wide.

Description

technical field [0001] The invention relates to a method for preparing an Ag-Al co-doped p-type ZnO thin film, belonging to the technical field of chemistry and chemical engineering. Background technique [0002] The research on modern sol-gel technology began in the middle of the 19th century, using sol and gel to prepare single-component compounds. Because the temperature required to prepare glass by this method is much lower than that of the traditional high-melting method, it is also called the low-temperature synthesis method of glass. In 1939 W. Geffcken and E. For the first time, Berger used the sol-gel dipping method to coat glass plates, prepared a coating that changes the optical reflection properties of glass, and obtained a patent, and proposed the sol-gel dipping coating process for the first time in the patent literature. In 1959, German Special Glass AG began mass production of automotive rearview mirrors using sol-gel dipping coating technology. In 1962 H...
