Abstract

Abstract: Abstract : The pure and Er 3+ -modified binary Pb(Zn1/3 Nb2/3 )O3 –9PbTiO3 (PZN–9PT) single crystals were grown by using the flux method. The phase structure of the as-grown single crystals at room temperature was confirmed by the x-ray diffraction analysis. The effect of Er 3+ addition on the electrical properties and upconversion luminescence of PZN–9PT was investigated. The rhombohedral to tetragonal phase transition temperature and the Curie temperature of the Er 3+ -modified PZN–9PT single crystals were 370 and 451 K, respectively. The coercive field E C at room temperature was evidently higher by 11.6 kV/cm than that of the PZN–9PT single crystals ( E C, ∼3.5 kV/cm). Furthermore, the green and red upconversion emission bands were obtained under the 980 nm excitation, which are related to ( 2 H11/2, 4 S3/2 ) → 4 I15/2 and 4 F9/2 → 4 I15/2 transitions.
