CdS nanoparticles have been synthesized by a chemical reaction route using ethylenediamine as complexing agent.The were characterized techniques such X-ray powder diffraction (XRD), scanning electron microscope (SEM), UV-VIS absorption spectroscopy, and photoluminescence spectroscopy.The edge for the bulk hexagonal is at 512 nm (2.42 eV).Comparing with CdS, it believed that blue shift in peak was caused quantum confinement effect.Photoluminescence measurements indicate show fluorescence band...
A one-pot method was used to synthesize CuInxGa1–xS2 nanoparticles by substituting In3+ with Ga3+. The samples composition of gallium ranging from 0% 100% were synthesized solving copper chloride, indium trichloride, acetylacetonate, and thiourea as precursors in 1-octadecene, oleylamine, oleic acid noncoordinating, coordinating, capping agent solvents, respectively. Depending on the chemical synthesis conditions, morphology as-synthesized obtained trigonal, semitrigonal, hexagonal,...
Monodisperse copper-iron-sulfide (CuFeS2) nanoparticles as the infrared light absorbing material (chalcopyrite, 0.65 eV), were synthesized based on facile, one step heating up method, by dissolving of CuCl, FeCl3 and SC(NH2)2 precursors in oleylamine (OLA) alone or combination with oleic acid (OA) 1-octadecene (ODE) solvent. The phase, size, morphology, size distribution controlled reaction conditions temperature. CuFeS2 characterized transmission electron microscopy, X-ray diffraction,...
Due to the growth of population and industrialization, a great number problems associated with producing industrial wastes have been created for both environment human beings. The waste management in Brujen park, located western part Iran, has investigated this study using environmental rapid impact assessment matrix technique. For purpose, effective activities components were classified. determination best scenarios least on was performed by developing possible disposal making calculations...
In this investigation, CuInS2 ternary compound was synthesized by injection of thiourea solution into a hot copper-indium solution. The CuCl, InCl3 along with (SC (NH2)2) were used as precursor dissolved in high boiling point solvent such oleylamine (CH(CH2)17NH2) and oleic acid (CH(CH2)16COOH) coordination capping agent, respectively. size, distribution shape optimized controlling some parameters the ratio to anion cation temperature instant injection. crystal structure, morphology, optical...

Abstract The limiting organic concentration (LOC) of zirconium (IV), which is the maximum possible metal species in phase without formation crud as a third phase, was determined under different experimental conditions such HNO3 aqueous and modifier (TBP or isodecanol) phase. Also, effect several diluents (orthoxylene, toluene, n-heptanes, n-dodecan, petroleum ether, chloroform, kerosene) solution aging on LOC have been investigated. results showed that depends dipole moment feed has...
