“…To fill this gap, in the present work, the polycrystalline powder of Eu2(SO4)3 has been synthesized and the crystal structure of the sulfate has been determined for the first time. It might be well to point that much research on synthesis of materials for various applications by different methods, including the green chemistry approach, were conducted resently [44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62][63]. However, to provide synthesis of stoichiometric Eu2(SO4)3 compound, the precipitation approach was used in the present study.…”

Eu2(SO4)3 was synthesized by chemical precipitation method and the crystal structure was determined by Rietveld analysis. The compound crystallizes in monoclinic space group С2/с. In the air environment, Eu2(SO4)3 is stable up to 670°C. The sample of Eu2(SO4)3 was examined by Raman, Fourier-transform infrared absorption and luminescence spectroscopy methods. The low site symmetry of SO4 tetrahedra results in the appearance of the IR inactive ν1 mode around 1000 cm-1 and ν2 modes below 500 cm-1. The band intensities redistribution in the luminescent spectra of Eu 3+ ions is analyzed in terms of the peculiarities of its local environment.

“…Recently, the sublimation method as a novel route has been developed to synthesize organometallic compounds in nano-scale that are used as precursors for synthesis of metal oxide compounds by thermal decomposition [10,[25][26][27]. This process is simple and eco-friendly due to its properties such as lowtemperature of the reaction and free-solvent, as well as, using precursor in nano-scale is an advantage of it.…”

In this work, Ni(acac) 2 nanostructure was prepared through sublimation method that is a new method for the synthesis of nanomaterials. The temperature of sublimation is an effective parameter on morphology of products, so the role of this parameter on morphology and size of Ni(acac) 2 nanostructures was investigated. The uniform Ni(acac) 2 nanostructures were considered as an appropriate precursor for synthesis of nickel oxide nanoparticles (NiO NPs) by thermal decomposition method. Finally, NiO/ graphene nanocomposite (NiO/G) was successfully synthesized by the pre-graphenization route. The as-prepared products were characterized by various analyses such as: SEM, TEM, EDS, VSM, and XRD. The optical band gaps of the pure NiO and NiO/graphene nanocomposite were estimated about 3.3 eV, so these products were considered as semiconductors that can be used as photocatalyst. Increasing the surface and decreasing the possibility of (e-h +) recombination of nanocomposite were led to the better photocatalytic performance of NiO/graphene nanocomposite than pure NiO. According to the obtained results, degradation of methyl orange (MO) in the presence of NiO/graphene nanocomposite under UV and visible light as about 90.3% after 75 min, and 78% after 180 min, respectively.

“…These properties mainly determine potential uses of the complex. It is widely used as a chemical shift reagent in NMR processes, as a luminophore for latent fingerprint visualization, as a precursor for light-emitting material fabrication, etc. − Moreover, the complex has some potential as an agent for the separation of lanthanides by gas chromatography . The application area of Eu(fod) 3 is continuously expanding.…”
