CTO(Cadmium Stannate Oxide) thin film were deposited onto borosilicate glass by chemical spray pyrolysis. The structure of the film had been identified as polycrystalline Cd_(2), SnO_(4), having(l30) (310) (321) (041) and (341) planes.
The transmittanced of the films was more than 90% in visible range and the films reflect almost all of the infrared spectra beyond 2.8um . The refractive index of this film was 1.8 at 6,000Å and 2.2 at 5,l00Å. And the optical band gap were 2.85eV. Through annealing in Argon ambient the sheet resistance of the CTO films were lowed.
