“…Therefore, the polymeric chains have not been formed longer and local aggregation formed on the surface of the films with more roughness. In addition, MEA and DEA act as a complexing agent, also retarding the Zn(II) condensation; however, the presence of the amine also increases the pH, which should promote the formation of ZnO [20]. On the other hand, the properties of the films are not considerably affected by the pH of the sol in the present work due to low change of pH (Table).…”

The ZnO thin films were prepared from zinc acetate dihydrate as main precursor by using sol-gel method and deposited by drainage and dip coating technique. Four different routes and coating techniques were used for the preparation of samples. The morphology, optical, and structural properties of the sol-gel made ZnO thin films were studied with respect to the preparation of sol-gel route, drainage and dip coating technique. The microstructure of the ZnO thin films and the powders were analyzed by X-ray diffraction. The ZnO thin films prepared in this study were amorphous while its powders were polycrystalline with various diffraction peaks in the X-ray diffraction patterns. The morphology of the film was examined by using scanning electron microscopy. The surface morphology of the ZnO thin films strongly depends on preparation route and deposition technique. The optical characteristics of the samples were obtained by using UV-Visible spectrophotometer at 200-900 nm wavelength. The optical constants (refractive index, extinction coefficient etc.) of the ZnO thin films depend on preparation conditions. The photoluminescence spectra of the ZnO films show the band-edge and sub-band transitions.

“…ZnO nanoparticles exhibit excellent electrical, opticaland chemical properties, widely applied to produce semiconductors, optical devices, piezoelectric devices, surface acoustic wave devices, sensors, transparent electrodes and solar cells [4][5][6]. Besides, ZnO nanoparticles also exhibiting antimicrobial activities against Escherichiacoli and Staphylococcus aureus [7][8][9][10][11]. Several researchers reported doping of ZnO with metals such as Mn, Co, Cr, Cu, In and Laby various methods such as hydrothermal, sol-gel and coprecipitation method but only few reports are available ZnO doped with Al and Y [12][13][14][15][16].…”

Yttrium-doped ZnO nanoparticles were synthesized by co-precipitation method to investigate structural, optical and antibacterial properties. X-ray diffraction analysis confirms hexagonal (wurtzite) structure with average crystallite size between 16 and 30 nm. Optical energy band gap decreaseswith increasing Y-doping concentration. ZnO nanoparticles were found to be highly effective against S. aureus and Y-doped ZnO nanoparticles against E. coli, B. subtilis and S. typhi. Undoped and Y-doped ZnO nanoparticles are good inorganic antimicrobial agents and can be synthesized by cost effective co-precipitation method. Keywords: nanoparticles, ZnO, coprecipitation, antibacterial properties.

“…Zinc oxide (ZnO) is a versatile semiconductor material, with wide range of applications in photo electrochemical cells [5], lasers [6], and other electrical devices [7,8]. ZnO is a promising candidate for contact layers in next-generation thin-film photovoltaics because it is a lowcost, non-toxic, earth-abundant material with multiple solution deposition routes to the formation of thin films [9].…”

Abstract. We have designed and synthesized an efficient and novel photosensitive two small organic molecules with different lengths of methine units, cyano groups as the electron acceptor units, and amino groups as the electron donor units. Compound 1 was synthesized from benzaldehyde, malononitrile and hydrazine hydrate and benzaldehyde whereas compound 2 was synthesized from benzaldehyde, Dimedone and hydrazine hydrate and their thermal, phovoltaic and surface properties were studied. Then these small molecules were utilized for development of organic solar cells in FTO: ZnO: Organic compound: Electrolyte: Pt electrode pattern.
