摘要：
This work aimed to improve the energy storage properties of lead zirconate (PZ) thin films by doping titanium content. Thin films of Pb-(0.9)-Zr-(0.1) (PZ) and Pb-(0.9)-(Zr-0.05.Ti-0.05)O-2 (PZT) were grown epitaxially on a glass substrate by a sol-gel colloidal route at low temperature. The structure of the obtained nanocrystals was checked by X-ray diffraction (XRD), transmission electron microscope (TEM), and electron diffraction (ED). Nanocrystals were distributed evenly of 7 +/- 0.2 for PZ and 7.5 +/- 0.2 for PZT nm in size and were closely packed. The frequency dependence of dielectric properties and the ferroelectric characteristics were detected. The energy-storage density and energy-storage efficiency estimated from hysteresis loops were about 35.15 J/cm(3) and 65.8% for (PZ) and 68.25 J/cm(3) and 66.6%for (PZT) for one layer, respectively. Results showed that the titanium content had a clear effect on the dielectric properties, ferroelectric properties, and structural properties, and on the other hand, (PZ) and (PZT) thin films had a potential application in the energy-storage device.
