| Popis: | The Zr3d spectrum in the XPS measurement of PZT ceramics was found to vary according to their crystalline phases. The Zr3d spectrum of the rhombohedral phase was deconvoluted to the Zr3d5/2 profile at 181.3±0.2eV (denoted as A1) and the Zr3d3/2 profile at 183.6±0.2eV (A2), corresponding to a single chemical state. In contrast, those of both the tetragonal phase and the MPB were deconvoluted to four profiles, Zr3d5/2 at 182.1±0.2eV (B1) and Zr3d3/2 at 184.5±0.2eV (B2) in addition to A1 and A2, corresponding to double chemical states. The area ratios of (B1+B2)/ (A1+A2) for the tetragonal phase and the MPB were 0.6 and 0.3, respectively. These results indicate that XPS has potential for a novel analytical application to PZT ceramics. |
