Abstract PLZT 5/30/70 sols for thin film deposition have been prepared from lead oxide, lanthanum nitrate and transition metal n-butoxides in a series of etheralcohols. After the low temperature heat treatment at 200°C for 2 minutes and at 400°C for 5 minutes the PLZT 5/30/70 thin films crystallize in the perovskite phase and exhibit ferroelectric response. To our knowledge, this is the lowest crystallization temperature of perovskite phase observed for titanium rich PLZT.
