The evolution of structure and chemical distribution in sol-gel derived Pb(Zr{sub 0.53}Ti{sub 0.47})O{sub 3} thin layers was monitored by x-ray diffraction, analytical electron microscopy, and diffuse reflectance Fourier transform infrared spectroscopy. Electron microscopy confirmed the as-deposited coatings were amorphous with short-range order. Medium-range order developed on heat treatment, and chemical heterogeneity was observed at the nanoscale. The extent of compositional heterogeneity decreased with increasing temperature. Above 500 {degree}C, the coatings crystallized into an intermediate phase which converted to the perovskite phase above 600 {degree}C.
