AN INQUARY STUDY OF NiO FILMS DEPOSITED WITH SOL-GEL SPIN COATING

Y incorporated nickel oxide thin films have been deposited via sol-gel route by using spin coater. The structural, morphological and optical properties of films have been inquired. The films had nano-sized polycrystalline cubic structure. The optical characterizations indicated that the band gap and Urbach energy continuously went up with Y contribution. The present investigation reveals the properties of nickel oxide are healed and controlled with Y contribution and these films are probably good candidates for various applications
