Abstract

Nano-structure BaTi0.9Sn0.1O3 (BTSO) doped with Nd3+ (BTSO: 5N) and co-doped with Nd3+/Yb3+ ions (BTSO: 5NY), were prepared using the modified sol-gel method in powder form and annealed at 1050oC in air for 4h. Their structural, morphological, photoluminescence and dielectric properties studies were investigated. The crystallite sizes from XRD and TEM found to be decreased upon doping with Nd3+and Nd3+/Yb3+ ions, respectively. FTIR results showed enhancement of crystallinity and absence of carbonates upon increasing Yb3+ ions. TEM micrographs show that particles have spherical shape with small size within the nano-structure phase. FESEM microphotographs showed a density increase due to replacement of Nd3+and Yb3+ions at the B-site (Ti4+). From photoluminescence it was obtained that emissivity quenched by increasing Yb3+ ions concentration as the Nd3+ act as sensitizer for Yb3+. Cuire temperature (Tc) of doped and co-doped samples shifted to lower values. Besides, their permittivity and AC conductivity increased in comparison with BTSO.
