Preliminary results regarding the electrochemical behavior of Se(IV) in sodium citrate solution on a polycrystalline SnO 2 electrode are presented. A schematic diagram of the energy levels for an n-type SnO 2 electrode in contact with the working electrolyte was constructed. The results of cyclic voltammetry (CV) show that SeO 3 2− reduction occurs through a surface state in a complex multistep pathway. After a minute amount of Se is deposited, the electrode is expected to behave locally like a Schottky diode in contact with the solution. CV analysis and current transient results indicate that selenium growth on the polycrystalline SnO 2 surface proceeds without nucleation. A thin Se film obtained at a potential of −0.8 V vs. Ag|AgCl, KCl (sat) was analyzed by lateral force and atomic force microscopy.

Thin MoO 2 films were electrodeposited on a selenium pre-deposited SnO 2 |glass plate. The photoelectrochemical properties of MoO 2 films were investigated in 0.1 M Na 2 SO 4 solution by the ultraviolet-visible spectrophotometry, linear sweep voltammetry, and altering current impedance measurement techniques. It was found that under illumination with the incident light of λ=366 nm, the photo response of the MoO 2 |SnO 2 |glass electrode resulted from the MoO 2 layer, while the SnO 2 layer served as a sink for photogenerated charge carriers. The MoO 2 film exhibited ntype conductivity. A schematic band structure diagram of MoO 2 in 0.1 M Na 2 SO 4 solution was constructed. The flat band potential (E fb ), the donor concentration (N D ), the photogeneration current efficiency depended on MoO 2 film thickness. The [Fe(CN) 6 ] 4−/3− redox PEC cell with MoO 2 | SnO 2 |glass plate as a photoanode was constructed. Power output characteristics such as the open circuit voltage (V OC ), short circuit current (I SC ), the fill factor (FF), and the lightto-electrical conversion efficiency (η) were determined. The maximum light-to-electrical conversion efficiency exhibited by the PEC cell was 0.94 %.

“…This difference in crystallite size can be ascribed to the difference in the lattice constants obtain. The strain value δ and the dislocation density ɳ can be evaluated by using the following relations [15,16], their values were tabulated in Table 1: (2) (3) The results revealed that the strain and dislocation density are decreasing with the increase in crystallite size. The SEM technique was employed to explore the size and distribution of particles in the materials.…”

ABSTRACT. In this paper, we report on the fabrication and properties of undoped and 8.4% Er 3+ -doped ZnO nanoparticles synthesized by laser ablation in ethanol at laser fluence values 2.92 J/cm 2 . The synthesized nanoparticles are characterized by structural properties using X-ray diffractrometer, scanning electron microscope and the optical properties are carried out through UV-Visible spectrophotometer. The X-ray diffractrometer pattern indicates that these nanoparticle were polycrystalline in nature with a hexagonal (wurtzite) phase. SEM reveals that The synthesized ZnO and Er-ZnO NPs have a spherical shape. Moreover, the optical band gaps calculated through UV spectroscopy are found to be decreased with doping from 3.3 to 3.2 eV .
