Nanocrystalline 10 Wt% Bi2O3 doped Sr2CoO4 was prepared by sol-gel citrate method, and calcined at different temperature. The Sr2CoO4 nanoparticles were characterized by Impedance analysis, and Gas sensing. The ac conductivity was studied for the sample 10 Wt% Bi2O3 doped Sr2CoO4 calcined at 650OC, at temperatures 100 to 700OC and over a wide range of frequencies (50 Hz to 200 kHz). Experimental results indicate that the ac conductivity depend on temperature, frequency and concentration of dopent. Nanocrystalline 10 Wt% Bi2O3 doped Sr2CoO4 was found to be good ammonia sensor with high sensitivity and selectivity.
