ABSTRACT:
This invention encompasses methods and reagents for making PT, PZT, and PLZT as well as their extrinsic ions doped powders and thin films. In particular, the invention includes methods for localized laser annealing of PT, PZT, PLZT films to the surface of materials to provide articles useful in electronic devices such as high value capacitors, optical switches, wave guides, and the like. A 15-25% by weight of PT/PZT/PLZT in about a 5-10% acetic acid solution having an effective wetting agent of a surfactant has been found to be a superior isolation for making both powders and thin films, especially thin films for laser writing.
