Effect of temperature and deposition time on the optical properties of chemically deposited nanostructure PbS thin films

Effect of Deposition Time on the Optical Characteristics of Chemically Deposited Nanostructure PbS Thin Films

Optical properties of (Pb 1- x Mn x S) 1- y Fe y materials from first-principles calculations

Manganese sulfide thin films were chemically deposited from an aqueous solution containing manganese sulfate, sodium thiosulfate and sodium tartrate. The influence of deposition time (2, 3, 6 and 8 days) on the properties of thin films was investigated. The structure and surface morphology of the thin films were studied by X-ray diffraction and atomic force microscopy, respectively. In addition, in order to investigate the optical properties of the thin films, the UV-visible spectrophotometry was used. The XRD results indicated that the deposited MnS2 thin films exhibited a polycrystalline cubic structure. The number of MnS2 peaks on the XRD patterns initially increased from three to six peaks and then decreased to five peaks, as the deposition time was increased from 2 to 8 days. From the AFM measurements, the film thickness and surface roughness were found to be dependent on the deposition time.

Influence of deposition time on the properties of chemical bath deposited manganese sulfide thin films

In recent years, much attention has been emphasized on research to produce thin films using pulsed laser deposition. Therefore, the main objectives in this review were to address some important points such as the influence of different growth conditions on the properties of films using this method. The advantage of this method was discussed which including it could control the dimensions and display good crystallinity. The obtained experimental results from published articles were discussed and analyzed. So that, readers can know that this method could be used to prepare binary, ternary and quaternary films. Lastly, the power conversion efficiency of fabricated solar cells was reported in order to study these films could be applied in solar cell applications.
