Defect enhanced optic and electro-optic properties of lead zirconate titanate thin films

Pb(Zr1-xTix)O3 (PZT) thin films near phase morphotropic phase boundary were deposited on (Pb0.86La0.14)TiO3-coated glass by radio frequency sputtering. A retrieved analysis shows that the lattice parameters of the as-grown PZT thin films were similar to that of monoclinic PZT structure. Moreover, the PZT thin films possessed refractive index as high as 2.504 in TE model and 2.431 in TM model. The as-grown PZT thin film had one strong absorption peak at 632.6 nm, which attributed to lead deficiency by quantitative XPS analysis. From the attractive properties achieved, electro-optic and photovoltaic characteristic of the films were carried out.
