Nanoparticles of pure and Transition metals doped (Co, Ni and Cu) BiFeO{sub 3} of the composition BiFe{sub 0.9}A{sub 0.1}O{sub 3} (A = Co, Ni and Cu) have been successfully synthesized by sol gel auto combustion method using citric acid as a chelating agent and calcinated at 300°C. Microstructural analyses were done by XRD, TEM and SEM techniques. The crystallite size was resolute by powder X-ray diffraction technique whereas, UV-VIS technique was used to study the optical properties and band gap (Eg) of all samples. The variation of a. c. conductivity has been studied as function of frequency. It was observed that doping causes decreases in the ac conductivity of the nanoparticles as compared with the pure nanoparticles. It was also observed that doping of Transition Metals affects the optical properties effectively and band gaps were also increased.
