“…An analysis of the XRD spectra made it possible to obtain numerical values and determine the phase ratio in the samples (Table .). The phase composition of the FC, NH3, EA, DEA, and Pyr samples (weight fractions of phases, C, wt %) was determined as the result of full profile Rietveld refinements of crystal structures , using the obtained XRD patterns. The precision of phase composition determination for this method is ±2–3 relative %.…”

This work is aimed at studying the fundamentals ensuring the formation of high-quality functional printed copper layers at low temperatures. The paper describes the decomposition of copper formate and its ligand-based complexes: ammonia, ethylamine, diethylamine, and pyridine. Structural and thermal features of the samples were studied by differential thermal analysis, thermogravimetric analysis, and X-ray diffraction analysis. Based on the results of experimental data and quantum-chemical calculations as well, the main features of the reactions of decomposition of the studied samples have been proposed. Aspects of the main factors reducing the decomposition temperature of complex compounds have been identified and described. Based on the results of the study, a selfconsistent model which describes the limits of the existing models of the decomposition process of copper formate and its complex compounds is proposed in the work.

New Eu^III Pyromellitic Metal–Organic Framework of Intense Red-Orange Luminescence and High Thermal Stability for Marking in Gunshot Residues

et al. 2020

The preparation, general characterization, and experimental and theoretical photoluminescence investigations of a new europiumIII metal–organic framework [EuHbtec] n 1 supported by 1,2,4,5-benzenetetracarboxylic acid, H4btec (pyromellitic acid), are discussed in this work. The crystal structure was obtained from X-ray powder diffraction (XRPD), with the data collected at the MCX beamline of ELETTRA synchrotron. In this structure, the monoprotonated Hbtec3– ligands act in three different coordination modes to EuIII centers: μ2-η1:η2 chelating/bridging, η2 chelating, and η1 monodentate modes. The three-dimensional (3D) network is constructed by secondary building units (SBU) chains, connected through carboxylate groups of the Hbtec3– ligands. Using the Sparkle/RM1 model, the ground-state geometry of [EuHbtec] n 1 was calculated in the solid phase and then used to obtain the several investigative spectroscopic parameters. This study demonstrates that intense luminescence occurs through ligand sensitization. The exceptional thermal stability is proven by thermogravimetric analysis, with the network collapsing at 489 °C, the largest among the congener compounds. Thus, by combining its intense emission and high thermal stability, [EuHbtec] n 1 was utilized for marking of gunshot residues (GSRs), with its preliminary tests showing very promising results for applications in forensic contexts and public safety.

“…Crystal structure of the materials was evaluated by X-ray diffraction (XRD) in Bragg-Brentano geometry using a Philips X-Pert diffractometer; the patterns were acquired with 40 kV and 30 mA, using Cu K (=0.15418 nm) radiation and the scanning angle 2 varied between 20° and 80°, with 0.015° step. Lattice parameters, crystallite sizes, micro strain and preferential growth orientation were obtained through the Rietveld refinement method [27]. The refinement of XRD patterns were performed through the free software Fullprof, the criteria and sequence of refinement was achieved following the method proposed by Fuentes [28].…”

When tin oxide thin film is doped with Zn, it grows textured and improves its mechanical properties. The material was synthesized on alkali-free borosilicate glass substrates by spray pyrolysis technique. The elemental composition was determined by X-ray energy dispersive spectroscopy and X-ray photoelectron spectroscopy. The morphology and microstructure of films were examined by electron microscopy techniques, they shown different shapes of crystalline particles according to the dopant content. From X-ray diffraction patterns processed by Rietveld refinement methodology was determine lattice parameters, crystallite sizes and micro strain; it showed that the textural growth of the films depend on the Zn dopant quantity content. The mechanical property was studied as a function of dopants amount, it enhancement due to the texture direction growth. For optimized Zn doped quantity in the film, local measurement of hardness and elastic modulus increased from 12 to 23 GPa and from 137 to 195 GPa, respectively. According to the Zn content, the materials show good correlation between elastic module values and (200) texture growth direction parallel to the substrate.
