Abstract
Thin films of dicadmium stannate spinel (Cd2SnO4) were deposited on glass substrates using a dip-coating technique. The films were transparent to visible light (90%) and electrically conductive. XRD showed that annealed films consisted of a single cubic spinel phase only when they were prepared from a solution with the composition of Cd:Sn = 2.5 and fired at a temperature of 400-500 C. The Cd:Sn ratio, firing temperature, and post- deposition annealing sequence were crucial for the formation of a single phase, which is vital to obtain optimal optical and electrical properties. A resistivity as low as 3.3 x 10 exp(-4) ohm.cm could be obtained after annealing. 59 refs.
