Preparation and characterization o f nanocomposite Ti02/Sn02 films

Abstract

This work presents the preparation of nanocomposite Ti02/Sn 02films by using spray pyrolysis and followed by sol-gel technique from T ÌC I4 and SnCU solutions. Obtained film s were characterized by XRD, SEM and photoconductivity measurement. It was found that in this method the nanocomposite Ti 02/Sn 02films were constituted o f nanosized TÌO2 and SnOa surrounded the TÌO2 grains. The obtained nanocomposite Ti02/Sn 02materials were shown to have the photoconducting properties. A reason of these novel properties was discussed and practical applications o f nanocomposite Ti02/Sn02films were showed.
