A novel electro-codeposited film was homogeneously obtained on an indium tin oxide (ITO)-coated glass electrode by cathodic polarization of a solution of 2,9,16,23-tetracarboxyphthalocyaninatomagnesium(II) ( Mg II taPc ), N,N′-4-hydroxyphenyl-3,4,9,10-perylenetetra-carboxylic-diimide (4-hph-PTC) and ZnCl 2 as supporting electrolyte in N,N-dimethylformamide (DMF). The cyclic voltammogram for the codeposited film showed a reduction at −0.8 V vs SCE which was assigned to the reduction of Mg II taPc and one at −1.5 V vs SCE which was assigned to the reduction of 4-hph-PTC. A device based on the codeposited film was prepared by the formation of an aluminum electrode on the codeposited film. The device exhibited rectification and photoconduction. The results suggest that the codeposited film forms a number of p-n junction interfaces which are distributed on the ITO electrode.

Chemically-modified Indium Tin Oxide (ITO) coated glass substrates were fabricated by depositing Nafion thin films doped with tris (2,2’-bipyridyl) ruthenium(II) dichloride hexahydrate via drop coating deposition technique. The Nafion volume concentration in the film is 1% (v/v) and the mediator concentration is 5 mg per 1 mL Nafion. The chemically-modified electrodes were characterized by cyclic voltammetry (CV) and were used as working electrodes to detect varying concentrations of copper (Cu2+) and zinc (Zn2+) in a 0.1 M NaCl supporting electrolyte solution via Anodic Stripping Voltammetry (ASV). Cu2+ and Zn2+ ions were successfully determined by ASV. The limits of detection for Cu2+ and Zn2+ were 0.1 ppm and 0.7 ppm, respectively. The modified electrodes were used to determine the presence of Cu2+ and Zn2+ in different real water samples. The presence of Cu2+ was successfully determined in deep well, lake, and tap water samples, while the presence of Zn2+ was successfully determined in sea and tap water samples. Atomic Absorption Spectroscopy (AAS) results confirm the presence of Cu2+ and Zn2+ in the samples.

ZnS thin films were deposited on indium–tin-oxide (ITO) coated glass substrates by a chemical bath deposition method. Then the ZnS/ITO slides were immersed in the solution containing 6 mM phosphate buffer solution (pH 7.4), sodium polyacrylate (0.01% w/w), and 0.24 mM AgNO3 at 37°C for 3 h to growth Ag2S films on the surface of ZnS/ITO slides. The absorption band of Ag2S/ZnS/ITO slide displays a considerably blue-shifted. The X-ray diffraction analysis demonstrated the presence of acanthite Ag2S on the surface of ZnS/ITO slides, which is consistent with the cyclic voltammetic data.
