Cds Thin Films

CdS thin films were prepared by chemical-bath deposition (CBD) from a bath containing thiourea, acetic cadmium, ammonia and ammonium acetate in aqueous solution onto glass substrates at 80°C with stirring. The influence of pH value on the surface morphology and optical properties of the CdS thin films was investigated. Step height measurement instrument, scanning electron microscopy (SEM), X-ray diffraction (XRD), spectrophotometer and digital four-point probe resistance measurement were used to characterize their thickness, surface morphology, crystal structure, electrical and optical properties. Uniform CdS thin films were obtained when pH=11.6. There are obvious diffraction peaks at 26.04° when pH is 11.6. The transmittance increases as the pH values increase. The experiment show that pH value play a vital role in the properties of the CdS thin films.

Deposition Conditions

Magnesium hydroxide (Mg(OH)2) thin films were deposited by the drop-dry deposition (DDD) method using an aqueous solution containing Mg(NO3)2 and NaOH. DDD was performed by dropping the solution on a substrate, heating-drying, and rinsing in water. Effects of different deposition conditions on the surface morphology and optical properties of Mg(OH)2 thin films were researched. Films with a thickness of 1−2 μm were successfully deposited, and the Raman peaks of Mg(OH)2 were observed for them. Their transmittance in the visible range was 95% or more, and the bandgap was about 5.8 eV. It was found that the thin films have resistivity of the order of 105 Ωcm. Thus, the transparent and semiconducting Mg(OH)2 thin films were successfully prepared by DDD.
