Abstract
In2S3 films were prepared by spray pyrolysis technique at various substrate temperatures (T sub) and the spray solutions were mixtures of indium chloride (InCl3) and thiourea (SC(NH2)2). The films are preferentially oriented along the (220) plane and are of polycrystalline In2S3 with a cubic crystal structure. The refractive index dispersion curves of the films obey the single oscillator model and oscillator parameters changed with substrate temperature. The most significant result of the present study is to indicate that substrate temperature of the film can be used to modify the optical band gaps and optical constants of In2S3 films. The effect of T sub on the optical dispersion of these films has been investigated.
