Deskripsi
Lanthanum modified lead zirconate titanate (abbreviated as PLZT) Electro-Optical ceramics with various Bi concentration were prepared by a hot-press process. The PLZT ceramic samples all present a single perovskite structure with no second phase detected. Bi<sup>3+</sup> ion was considered to mainly enter the A-site of perovskite ABO<sub>3</sub> structure of PLZT ceramics by the X-Ray Diffractionanalysis. The maximum permittivity (<i>ε</i><sub>m</sub>) of the PLZT samples decreased obviously as Bi concentration increased, while their remnant polarization (<i>P</i><sub>r</sub>) decreased slightly. In particular, the PLZT sample with 0.14 wt% Bi doping presented a higher optical transmittance 61.8% (<i>λ</i> = 633 nm), and its electric-induced light scattering performance was found to be improved obviously, the maximum light deduction value of ~47.6% was obtained.
