Abstract

The invention provides an aluminum doped zinc oxide target and a preparation method thereof. The preparation method comprises the steps of dissolving aluminum salt and an adhesive agent in a solvent, adding zinc salt powder, stirring, drying, obtaining mixed powder, performing compression molding and sintering on the mixed powder sequentially, and obtaining the aluminum doped zinc oxide target. The preparation method is simple, low in production cost and suitable for industrial development, and the prepared aluminum doped zinc oxide target is higher in quality.

Description

technical field [0001] The invention relates to photoelectric functional materials, in particular to an aluminum-doped zinc oxide target material and a preparation method thereof. Background technique [0002] With the rapid development of semiconductors, computers, solar energy and other fields, transparent conductive oxide (TCO) thin films can be widely used in various displays and various optoelectronic devices due to their good conductivity and high transmittance. The most widely used transparent conductive film in the industry is tin-doped indium oxide (ITO, TindopedIndiumOxide) film, but it has the disadvantages of high price, rapid decrease of transmittance at high temperature, and easy reduction in hydrogen plasma; and ZnO The price is low, the raw material is abundant, and it is more stable than ITO in a hydrogen ion atmosphere. It can not only be made into a good semiconductor and piezoelectric film, but also can be made into a good transparent conductive film thro...
