CdS and CdS:Sn thin films were successfully deposited on glasssubstrates by spray pyrolysis method. The films were grown atsubstrate temperatures 300 C°. The effects of Sn concentration on thestructural and optical properties were studied.The XRD profiles showed that the films are polycrystalline withhexagonal structure grown preferentially along the (002) axis. Theoptical studies exhibit direct allowed transition. Energy band gapvary from 3.2 to 2.7 eV.

In this work, thin films of undoped and Ag-doped CdO with (1and 3) wt.% were prepared by using spray pyrolysis method on glass substrate at of 350ºC with films thicknesses of (160-190) nm using spraying rate and pyrolysis time is 5 ml/min an 5sec respectively. The X-ray diffraction investigated the structural types of the CdO thin films after and before doped by Ag, XRD analysis showed that CdO:Ag films are highly polycrystalline and exhibit cubic crystal structure with (111) preferred orientation. However, the peak for all CdO:Ag films became more intense with a slight variation. The optical properties measure by ultra violet spectra, the optical study shows the spectral transmission and the optical energy band gap increases from 64.77% and 2.50 eV to 71.11% and 2.70 eV respectively depending upon the Ag content in the films, in contrary with the absorbance that increases with the decrease in wavelength and decreases with the increasing Ag doping concentration.

In this research Bi2S3 thin films have been prepared on glass substrates using chemical spray pyrolysis method at substrate temperature (300oC) and molarity (0.015) mol. Structural and optical properties of the thin films above have been studied; XRD analysis demonstrated that the Bi2S3 films are polycrystalline with (031) orientation and with Orthorhombic structure. The optical properties were studied using the spectral of the absorbance and transmission of films in wavelength ranging (300-1100) nm. The study showed that the films have high transmission within the range of the visible spectrum. Also absorption coefficient, extinction coefficient and the optical energy gap (Eg) was calculated, found that the film have direct energy gap equal to 2.8 eV.
