More details: During the electromigration of lithium ions from molten LiCl?�?KCl mixtures into FeS three of the phases formed are Li2FeS2 (X phase), Li3Fe2S4 (Z phase), and LiK6Fe24S26Cl (J phase). These phases and the copper-substituted X phase (Li1.33Cu0.67FeS2) were prepared by high-temperature solid-state reactions between the respective metal sulfides, and their electrical conductivities were measured over temperatures ranging from 20 to 550??C. The results show that the X and copper-substituted X phases are semiconductors with conductivities and activation energies in the range of 0.1 to 10 (ohm-cm)?��1 and of 8 to 21 kJ mole?��1, respectively. The Z phase has a conductivity orders of magnitude less, and the J phase decomposes. A change in the slope of the Arrhenius plot occurs at 225??C, probably associated with some residue of the phase change in the FeS component. The electronic structures determined with photoelectron spectroscopy reveal the presence of two valence states for iron in the X, copper-substituted X, and Z phases. The valence bands consist of overlaping Fe(3d), Cu(3d), and S(3p) electronic densities.

More details: High-quality and high-yield 3D flower like indium sulfide (In2S3) nanostructures with cubic structure were synthesized by a wet chemical route, without using any surfactant and organic solvents at 160\&\#xa0;??C for 12\&\#xa0;h, by using InCl3 and 2-aminothiophenol (2-ATP) as starting reagents. The obtained In2S3 with different morphologies and size was characterized by X-ray diffraction pattern (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), and ultraviolet?��visible (UV?��vis) spectroscopy. The effects of reaction parameters, such as temperature, precursor concentration and reaction time on the morphology, and particle size of products were investigated. Our experimental results showed that temperature and time reaction played key roles in the final morphology of In2S3. The morphology of In2S3 structures could be changed from one-dimensional (1D) structures to three-dimensional (3D) structures by increasing reaction time to 24\&\#xa0;h. In the present study the optical properties 3D In2S3 structures were investigated. 3D structure,Hydrothermal,Indium sulfide,Nanostructure,Semiconductor
