The Transparent Conductive Oxide Materials and Their Application

Al-doped zinc oxide (AZO) and pure ZnO nano powder have been fabricated by a novel sol-gel method. Under propriety conditions such as concentration of reactant, right PH value, dryness, right annealing temperature and time, we can get the AZO nano powder with a controllable grain size (~ 20 nm), single phase structure and uniformity dispersion. Some related work has been published on 《Journal of Sol-Gel Science and Technology》(DOI: 10.1007/s 10971-009-1959-5). Furthermore, we can also prepare a high density AZO target (>97%) with a sintering temperature lower than 1000℃, it can establish a good foundation for preparing ZnO conductive nano powder in a large scale.
