Abstract A simple and rapid process for synthesizing (Pb,La)(Zr,Ti)O3 (PZT, PLZT, and PLT) precursor solutions has been developed. This process, termed the “basic route to PLZT” (or BRP) process, offers several advantages over standard methods, including rapid solution synthesis (〈10 min), use of commercially available materials, film production under ambient conditions, ease of lanthanum dissolution at high concentrations (〈1 min), and no heating requirements during solution synthesis. The PLZT precursor solution synthesis involves dissolution of lead acetate (or acetyl acetate) in pyridine followed by addition of a pre-dissolved mixture of titanium and zirconium iso-propoxide in toluene. The lanthanum source can then be added and, depending on the precursor, total synthesis time was 〈10 min. The preferred lanthanum starting material is a highly soluble bis(iso-propyl)aryloxide complex; however, this compound is extremely air and water sensitive. The compositions investigated in this study include PZT 40/60, PLZT 3/30/70, 5/30/70, and 10/40/60, and PLT films with 10–20 mol % La. All films were crystallized at 650 19°C and exhibit ferroelectric properties comparable to films produced by other techniques which require higher crystallization temperatures.
