The Structure and Optical Properties of Dy3+ Doped PLZT Ceramics

The polycrystalline Dy3+ doped PLZT ceramics with compositional formula [Pb0.88 (La1-xDyx)0.12](Zr0.40Ti0.60)O3, were prepared by hot-pressed method. Effects of Dy3+ 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 Dy3+ content increased, the optical transmission was found to decrease, and the refractive index was raised slightly.
