Anharmonic lattice dynamics and structural phase transition of α-AlF3
2024年4月15日 · In this work, we focused on the anharmonic lattice dynamics of α -AlF 3 by combining X-ray diffraction, in situ Raman spectra and first principles calculation. The Rietveld refinement showed that the displacement of F atom is about as two times as that of Al atoms even at room temperature.

AlF3-coated Li1.134Ni0.3Mn0.556O2 and Li1.2Ni0.2Mn0.6O2 delivered a capacity of 225 and 248 mAh g⁻¹, respectively, stable over the 55 cycles investigated.
Spectroscopic characterization of crystalline AlF3 phases
Its crystal structure (aAlF3, space group R3̄c) consists of corner-shared {AlF6}—octahedra forming a three-dimensional network. As shown by X-raydiffraction, DSC-Raman and EPR measurements, the matrix undergoes a reversible phase …
In Situ X-ray Diffraction and Solid-State NMR Study of the …
2001年2月2日 · In situ XRD experiments of the catalytically inactive α-AlF 3 phase were performed to investigate the structural changes of this material, associated with the extent of tilting of the AlF 6 octahedra in this ReO 3 -related structure, as a function of temperature.
An XRD Phase Analysis of Al-F Re-Deposition Produced from Reactive Ion ...
The results show that the prepared re-deposition was composed of F and Al atoms, with 51.24 At% and 27.67 At%, respectively. XRD revealed that this was owing to the chemical formula AlF3, which has a rhombohedral crystal structure in the most stable alpha phase (α-AlF3).
In this work, we have prepared Cr3+ doped AlF3 fluorescent materials by a large number of experiments, and analyzed their XRD patterns. The detailed spectra and its lifetimes were reported. It indicates that AlF3:Cr3+ phosphor has the potential value of developing LED optoelectronic devices.
