Surface morphology by SEM of the PZT thin films obtained at different annealing temperatures from the Photosensitive
(a) and Seeded Photosensitive (b) solution systems. X-ray diffractograms of the films annealed at 600 °C are included. A scheme showing the respective crystallization mechanisms proposed for each system at different stages (i: photoactivated gel film; ii: amorphous oxide film; iii: crystalline PZT film) is depicted.
