Physicochemical properties of the PZT precursor solutions.
(a) UV absorption of the Photosensitive solution, where both Zr and Ti alkoxides have been stabilized with acetylacetone (see general molecular structure, where M = metal atom and R = organic substituent). (b) Particle size distribution of a seeds dispersion constituted by PZT nanopowders in ethanol. (c) Stability with time of the Seeded Photosensitive solution measured by light transmittance.
