研究目的
Investigating the crystal structure of the quaternary chalcogenide compounds CuCo2InTe4 and CuNi2InTe4, two new members of the I-II2-III-VI4 family.
研究成果
The crystal structure of the quaternary compounds CuCo2InTe4 and CuNi2InTe4 was determined using X-ray powder diffraction. Both materials crystallize in the tetragonal space group I 42m with a stannite-type structure.
研究不足
The study is limited to the structural characterization of the compounds and does not explore their physical properties or potential applications in detail.
1：Experimental Design and Method Selection:
The crystal structure of CuCo2InTe4 and CuNi2InTe4 was characterized by Rietveld refinement using X-ray powder diffraction data.
2：Sample Selection and Data Sources:
Nominally CuCo2InTe4 and CuNi2InTe4 samples were synthesized using the melt-anneal method. Stoichiometric quantities of Cu, Co, Ni, In, Te elements with purity of at least
3：99% were used. List of Experimental Equipment and Materials:
A PANalytical X’Pert Pro MPD powder X-ray diffractometer operating in Bragg-Brentano geometry using CuKα radiation with an average wavelength of
4：5418 ? was employed. Experimental Procedures and Operational Workflow:
The fusion process was carried out inside a furnace heated up to 1500 K at a rate of 20 K/h, with a stop of 48 h at
5：5 K. The ampoule was shaken using a mechanical system during the entire heating process. Data Analysis Methods:
7 The Rietveld refinement of the whole diffraction patterns was carried out using the Fullprof program.
