摘要

Indium sulfide (In2S3) thin films have been synthesized on glass substrates using the spray technique (CSP). The S : In molar ratio was varied from 1 to 4 in the starting solution. The Raman analysis confirms the formation of the beta-In(2)S(3)material and the absence of a secondary phase. The EDS analysis reveals that our layers are pure. The thin film surface is free of cracks, as observed in AFM images. Optical transmission achieved 80% in the visible and near infrared region. The refractive index (n) is affected by the changes in the S/In molar ratio. The optical parameters, single oscillator energy (E-0), dispersion energy (E-d) and high frequency dielectric constant (epsilon(infinity)), are calculatedviathe Wemple-DiDomenico model. In addition, the photoconductivity kinetics in In(2)S(3)films for S/In = 2 were investigated and analyzed. TheI-Vcharacteristics and the photoresponse were also studied.
