摘要：
In this work,water-based precursor solutions suitable for dip-coating of thick La;Zr;O;（LZO） buffer layers for coated conductors on Ni-5%W substrates with an inclusion of polymeric polyvinyl pyrrolidone were developed.The effect of varying percentage of the polymer addition on the preparation of the deposited films with maximum crack-free thickness was investigated.This novel water-based chemical solution deposition method involving polymers in two different chelate-chemistry compositions revealed the possibility to grow single,crack-free layers with thicknesses ranging from 140 to 280 nm,with good crystallinity and epitaxial growth.The effect of increasing polymer concentrations on the morphology and the structure of the films was studied.The appropriate buffer layer action of the films in preventing Ni diffusion was studied by X-ray photoelectron spectroscopy.
