“…For the deposition of thin CuS layers, various physical and chemical methods, including chemical bath deposition (CBD) [2,15,[24][25][26], vacuum evaporation [27], successive ionic layer adsorption and reaction (SILAR) [18,28] and spray pyrolysis deposition [6,11,16,[29][30][31][32] have been used. These different methods mainly affect the morphology of copper sulfide samples.…”

In this study, physical properties of copper sulfide thin films deposited on glass substrates by spray pyrolysis method at different temperatures (260°C, 285°C and 310°C) were investigated. The influence of annealing time on the physical properties of grown layers was also studied. According to FESEM images, the sizes of the compact copper sulfide grains were varied from about 100 nm to 60 nm. Hall effect and resistivity measurements confirmed that all samples had p-type conductivity. The XRD patterns showed that, together with the dominant digenite phase (Cu 1.8 S) in all samples, the copper-rich phases also appeared as a result of increasing substrate temperature. The optical UV-Vis spectra analysis showed that due to increasing the substrate temperature, the band gap of the layers was reduced from about 2.4 eV to 2.0 eV. We found that as a result of annealing at 400°C for 1.5 h in Ar atmosphere, the sample which was initially grown at 310°C with the highest copper content, totally transformed into the polycrystalline monoclinic chalcocite phase (Cu 2 S) with 3D nanoporous architecture.

“…It was found that the metal can form complexes very well with thiourea and substituted thiourea. Some of those complexes have been synthesized and studied by X-ray diffraction [8][9][10] . However, the electrochemical properties have not been thoroughly studied.…”

ABSTRACT:The complexes between copper(I) halides and N,N -diphenylthiourea have been investigated by cyclic voltammetry to compare their structure and behaviour in solid state with those in solution. The halides under investigation include chloride, bromide, and iodide. Chloride and bromide complexes did not show the redox reaction, suggesting that they formed the strongest bond with the metal and hence the oxidation was inhibited. In contrast, iodide behaved differently because of the two peaks of halide and trihalide oxidations. One peak disappeared, leaving the other halide-oxidized peak shifted to a more positive voltage due to the bonding with the metal. In solution, all complexes of N,N -diphenylthiourea were derived from the oxidation process and exhibited oxidation potentials shifted to positive values.

Source of materialAll chemicals used for the preparation of the title compound were of reagent grade quality. Experimental detailsHatoms bonded to Natoms were located in aFourier difference map and refined isotropically without restraints. Hatoms bonded to Catoms were positioned geometrically and allowed to ride on their parent atoms, with d(C-H) =0 .93 Å;a nd U iso (H) =1 .2 U eq(C). DiscussionThiourea and its derivatives have always attracted attention in recent decades [7][8][9]. In our previous research works on the coordination reaction of transition metal ions with thiourea derivatives [1-6], some unexpected coordination or metal cluster compounds were obtained. The structural characteristics and the differences between substituted groups on thiourea have potent influence on thiourea coordination reactions. Obviously, the structural analysis on thiourea derivatives and their coordination compounds is crucial for discovering the relationship between the novel coordination reaction and the structural characteristics of thiourea ligands and helpful to design and synthesize novel materials.As the most other aryl thiourea derivatives, the title compound has two obvious non-hydrogen atom planar substructures, i.e. the molecular plane composed by C2-C7, N3, O1 and O2, and that composed by N2, C1, N1 and S1 (figure, top). The first molecular plane, is composed by benzene ring and the nitro group with the mean derivation from plane 0.022 Å,and the second molecular plane is thiocarbonyl group with the mean derivation from plane 0.003 Å
