In this study we used chemical bath deposition method for deposited Sb2S3 thin films on glass substrate. The study analyzed the optical properties and structural characterization of Sb2S3 thin films. The structural properties were studied on the thin films by x-ray diffraction (XRD), Scanning electron microscope (SEM), Energy dispersive X ray Analysis (EDAX). The XRD pattern showed that the thin films were polycrystalline, and EDAX showed that the constituents of the element were found to be chemically balanced and convergent peak (ie, verification chemical balance of phase Sb2S3).The optical properties showed that the optical energy gap at 40°C is 2.8  eV ,and at 50 °C is 2.6 eV , and the optical transmittance at 40°C is %80,and at 50°C is reached about %60.    http://dx.doi.org/10.25130/tjps.24.2019.035

Chemical spray pyrolysis technique was used at temperature 250˚C with annealing temperature at 400C˚( for 1hour) to deposition tungsten oxide thin film with different doping concentration of Au nanoparticle (0, 10, 20, 30 and 40) wt.% on glass substrate with thickness about 100 nm. The structural and electrical properties were investigated. The structure properties shows that the films at substrate by x-ray diffraction (XRD) temperature (250˚C) was amorphous structure while at annealing temperature have a polycrystalline structure with the preferred orientation of (200) , all the samples have a hexagonal structure for WO3 and Au gold nanoparticles have a cubic structure .The mechanisms of dcconductivity of un-doped WO3 and doped with Au (10,20,30 and 40) wt.% thin films at the range (303 to 473) K have been discussed , there is decrease in conductivity with the increase in the doping concentration and hall measurements show that all films have a negative hall coefficient and nH increases with the increase of Au dopant ratio and decreasing in carrier mobility (μH) with increasing of Au .

In this research we study  the effect of Argon  Laser  Irradiation and annealing on the  some optical properties of SnO2 Thin film . These films were prepared by chemical spray pyrolysis  method. The film thickness was 1500 A°. optical properties such as (Reflection, Energy band gab, Absorption coefficient, Refractive index, and extinction coefficient) as a function of photon energy have been studied within the wavelength range (300-900) nm, using (u v-visible) Spectrophotometer, before  and after irradiation and annealing. it is found that the  optical properties were change .
