Antimony (Sb+3 ) modified PLZT were prepared through a sol-gel technique with a general formula, Pb 0.92 (La 1−z Sb z ) 0.08 (Zr 0.60 Ti 0.40 ) 0.98 O 3 ; z = 0.0, 0.6, and 1.0 (PLSZT) formula to investigate the change in physical parameters of PLZT on substitution of Sb+3 at La-sites. To confirm the formation of the compounds XRD data have been taken on the gel dried calcined PLSZT powder. The dielectric and electrical properties of the compounds were studied by a complex impedance spectroscopic method (CIS). The effect of dopant (Sb) even in a small percentage has changed all physical properties of the PLZT drastically.
