摘要：

Partially doping of Ce and Mn at Ba and Ti site of BaTiO3 was done to study the dielectric and impedance behavior of Ba1-xCexTi1-xMnxO3 (x = 0.1, abbreviated as BCTM0.1) ceramics. We approach through chemical method to prepare a homogeneous nanosized material. The materials have 10.87 nm, 9.70 nm average crystallite and particle size respectively. The X-ray diffraction and Raman and EDX studies were employed to identify the phase purity and composition. Ferroelectric property was studied at a function of frequency and temperature. The relaxor behavior was observed during dielectric and impedance spectroscopy study. The ac and dc conductivity were also studied. Good photocatalytic activity of BCTM0.1 was observed for congo red (CR) and titan yellow (TY) dye solution with the % of degradation efficiency >95% and >82% respectively.
