of macro- and nanocrystalline PbS and CdS have been described in literature. Among the chemical methods, chemical bath deposition (CBD) is of special interest because it is simple and highly efficient. CBD allows adjustable control of size and surface density of nanoparticles, and can be used for preparation of high-quality nanocrystalline PbS and CdS films [ 4 , 6 ]. This method has been shown to allow control of stirring period, reaction time, bath temperature, pH of solution, complexing agent and impurities [ 7 , 8 ]. Among several n-type semiconductor

the synthesis of CdS nanoparticles were cadmium chloride anhydrous (CdCl 2 H 2 O) as the source of Cd 2+ ions, thiourea (CS(NH 2 ) 2 ) as the source of S 2- ions and ammonia solution (NH 4 OH) as the complexing agent to control precipitation. To prepare CdS nanoparticles, the equimolar (0.2 M) aqueous solutions of the reactants, cadmium chloride and thiourea were prepared using double distilled water (Millipore, 15 MΩ·cm) separately. The ammonia solution (25 %) was added dropwise through a burette into 25 mL of cadmium chloride solution under slow stirring. It was
