Photoinduced second harmonic generation (SHG) in Au nanoparticle-deposited ZnO nanocrystallite (NC) films was explored by applying bicolor coherent treatment of a Nd-YAG laser with wavelength 1.06 µm and its SHG. We have established that coexistence of the ZnO and Au nanoparticles gives a substantially larger SHG output with respect to pure ZnO NC deposited(More)
The electron transfer dynamics and electrocatalytic behaviour of ferrocene-terminated self-assembled monolayers (SAMs), co-adsorbed with single-walled carbon nanotubes (SWCNTs) on a gold electrode, have been interrogated for the first time. Ferrocene monocarboxylic acid (FMCA) or ferrocene dicarboxylic acid (FDCA) was covalently attached to the cysteamine(More)
The temperature dependence of the electrical resistivity of amorphous Co80 xErxB20 alloys with x 1⁄4 0, 3.9, 7.5 and 8.6 prepared by melt spinning in pure argon atmosphere was studied. All amorphous alloys investigated here are found to exhibit a resistivity minimum at low temperature. The electrical resistivity exhibits logarithmic temperature dependence(More)
Zinc oxide (ZnO) thin films were grown on three kinds of substrates (copper, silicon and glass) by the SILAR method. The solution was prepared by using zinc sulphate ZnSO<sub>4</sub> and ammonia NH<sub>3</sub>. And for rinsing, we heated the distilled water at the temperature 80&#x00B0;C. The nature of substrate was found to have effect on the crystal(More)
Nanostructured titanium oxide thin films were fabricated directly by an anodic electrodeposition using an aqueous TiCl<sub>3</sub> solution. Structure and morphology of thin layers of TiO<sub>2</sub> deposited on stainless steel and annealed at different temperatures were characterized by X-ray diffraction (XRD) and microscopy techniques (SEM, AFM).
