Growth and characterization of cubic KTa1-xNbxO3 crystals

Abstract The top-seeded flux method was used to grow large size and good quality undoped, Cu or Fe doped cubic phase KTa 1- x Nb x O 3 crystals. The morphology, homogeneity, dielectric properties and electrooptic properties of these crystals have been investigated. The photorefractive properties of a Cu-doped KTN crystal have also been studied and the results obtained show that the diffraction efficiency of this crystal is above 50% at room temperature.
