CuInS2 nanostructures were synthesized by sonochemical route using (bis(salicylate)copper(II)) as a new copper precursor. The effects of different parameters such as sulphur source, solvent, power of irradiation and reaction time on the morphology of the products were investigated. Nanostructures were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), photoluminescence (PL) and Fourier transform infrared (FT-IR) spectroscopy. CuInS2 nanostructures paste was prepared by doctor's blade technique on the transparent conductive oxide (TCO). The fill factor (FF), open circuit voltage (V oc), and short circuit current (Isc) were obtained by I-V characterization. © 2014 Indian Academy of Sciences.

In this work, CuI micro/nanostructures have been successfully prepared via a simple precipitation route at room temperature. By using glucose as a clean reducing agent with different concentrations, CuI micro/nanostructures with various morphologies were obtained. Besides glucose, Na2SO 3, KBH4 and N2H4·H 2O have been applied as reductant. X-ray diffraction (XRD), scanning electron microscopy (SEM), photoluminescence spectroscopy, X-ray energy dispersive spectroscopy (EDS) and Fourier transformed infrared (FT-IR) spectroscopy were used to characterize the as-produced CuI micro/nanostructures. According to the XRD results, it was found that pure cubic phase CuI have been formed by using glucose. © 2013 Elsevier Ltd. All rights reserved.

For the first time, silver salicylate marked as [Ag(HSal)] was applied to fabricate silver selenide nanoparticles. This article describes a simple approach based on reaction between silver salicylate as an inorganic precursor, SeCl4, and hydrazine hydrate (N2H4.H 2O) via sonochemical route for the fabrication of silver selenide (Ag2Se) nanoparticles. The effect of preparation parameters such as pH, ultrasonic power, and reaction temperature on the morphology of the final products was investigated. Ag2Se nanoparticles were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and X-ray energy dispersive spectroscopy (EDS). © Taylor & Francis Group, LLC.

Co3O4 nanostructures were synthesized via a facile thermal treatment method by using the trans, trans, trans-[Co (py) 2(H2O)2(SCN)2] as a new precursor. In synthetic process Co-complex was synthesized by reaction of KSCN via trans, trans, trans-[Co(py)2(H2O)2(NO 3)2]. Results show that changing on temperature to 400°C caused to preferential growth and formation of the honeycomb nanostructures. Nanostructures were characterized by scanning electron microscope, X-ray diffraction, UV-visible, Fourier transformed infrared spectroscopy and alternating gradient force magnetometer. It's found that the Co3O4 nanostructures exhibit a ferromagnetic behavior with a saturation magnetization of 16.6 emu/xg and a coercivity of 251.4 Oe at room temperature. © Taylor & Francis Group, LLC.

Silver (I) salicylate complex marked as [Ag(HSal)] was prepared, characterized, and applied to fabricate AgSCN micro/nanostructures. The [Ag(HSal)] complex was synthesized by silver nitrate and sodium salicylate via a simple precipitation route. To obtain AgSCN micro/nanostructures, the [Ag(HSal)] complex and KSCN were mixed with molar ratio of 1:1 in the presence of ultrasound irradiation. Besides, the effect of sonication time and surfactant on the morphology and particle size of the products was investigated. In this work, polyvinyl pyrrolidone was used as surfactant to prepare star-like and flower-like AgSCN microstructures. The products were analyzed by FT-IR, XRD, EDS, SEM, and TEM.

In this work, nickel molybdate (NiMoO4) nanostructures have been synthesized by low-temperature sonochemical method. Simplicity, rapid reaction rate, controllable reaction conditions and safety of the technique as well as the uniform shape, narrow size distribution, and high purity of prepared nano-sized materials are some of the main advantage of this method. The benefit of using ultrasound radiation in combination with thermal treatment is high yield and purity of product. The effect of various parameters such as: power of ultrasound irradiation, concentration of initial precursors, sonication time, and surfactant on morphology, size and purity of products were investigated. The products were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, transmittance electron microscopy, and photoluminescence spectroscopy. This work provides a general, simple and effective method to control the composition and morphology of NiMoO4 nanostructures. © 2015, Springer Science+Business Media New York.
