The Structure and Optical Properties of By~(3+) Doped PLZT Ceramics

摘要

The polycrystalline Dy~(3+) doped PLZT ceramics with compositional formula [Pboss (La_(1-x)Dy_x)_(0.12)](Zr_(0.40)Ti_(0.60))O_3, were prepared by hot-pressed method. Effects of Dy~(3+) substitution on structural and optical properties were report here. All the samples have single phase with tetragonal structure, and the tetragonality was increased with content increased. As Dy~(3+) content increased, the optical transmission was found to decrease, and the refractive index was raised slightly.
