The mesoporous SBA-16 thin films were synthesized with ITO as the substrate under acidic condition.The prepared SBA-16 thin films with narrow pore size distribution have a body-centered cubic structure (Im3m space group).In recent years,ITO-coated glass or AAO has been used as the substrates for the electrodeposition of CdS,while work on using mesoporous molecular sieves films/ITO as the substrate has not appeared.In an electrolyte solution composed of CdCl₂ and Na₂S₂O₃ with a modulated pH value of 2~3, "flower-like" nanocrystalline CdS was electrodeposited on the surface of SBA-16 thin films/ITO electrode via the DC electrodeposition method at a constant potential of -0.7 V for 50 min.The morphology and structure of the products were characterized by SEM,TEM and the PL properties were tested.The results show that the nanocrystalline CdS was grown on the surface of the electrode and not in the mesopores and showed PL properties.
