In this work, the impact of ultraviolet/ozone (UV/O3) treatment on the structural and electrical properties of solution-processed thick-film lead-zirconium-titanate (PZT) was systematically investigated. Highly (111)-oriented PZT film was observed together with minor phases originated from (100) and (101) orientations. Improvements of electrical properties such as leakage current and hysteresis loop were obtained as well. It is believed that the UV/O3 treatment could facilitate decomposition and oxidation processes of PZT film at a gel state, which leads to suppression of impurities (such as carbon and hydroxide) in the resultant film. As a result, a compacted and high-density PZT film could be achieved. The result enables the use of low-cost and environment-friendly solution-processed PZT film for various applications instead of using conventional high-cost vacuum-based process.
