摘要

Electrodeposited cadmium sulfide (CdS) on nickel substrate of new properties from aqueous solutions of Cd~(2+) and S_2O_3~(2-) at 313 K has been obtained using cyclic voltammetric and potentiostatic techniques. The mechanism of the electrode reactions for the electrode-position of CdS has been evaluated and proposed. Energy dispersive X-ray florescence elemental analysis and X-ray diffraction investigations demonstrate that, the electrodeposited CdS is pure and hexagonal polycrystalline in nature, at our optimal conditions. Furthermore, the electrodeposited CdS is of n-type semiconductor was investigated and confirmed by Mott-Schotky test. Donor concentration (N_D) was determined to be 1.0 × 10~(17) cm~(-3). In this research we discovered that, the electrodeposited semiconductor CdS on Ni substrate has low resistivity and magnetic properties (became as a strong magnet) at the mentioned conditions. The photoelectrochemical measurements of the electrodeposited CdS on nickel electrode had been investigated at room temperature and under illumination giving good results.
