Synthesis Characterization and Gas Sensing Properties of Ni and Fe Modified Nanocrystalline SnO۲ Thick Film Sensors

Ni and Fe doped SnO۲ Nanocrystalline material were synthesized by co-precipitation method. We study the structural, morphological properties by XRD and SEM-EDS analysis of newly doped Ni doped SnO۲ and Fe doped SnO۲ material. After getting good results for this material, we study the gas sensing properties such as the stability, selectivity, response and recoverability after that which is utilized as gas sensor for the investigation of some toxic and volatile gases those are dangerous to the environment.
