Interactions of yttrium and lanthanum fluorides with other fluorides
2022, Journal of Fluorine ChemistryCitation Excerpt :In MF2-YF3 (M = Ca, Sr, Ba, Pb) systems, the corresponding fluorite solid solutions M1-xYxF2+x are ordered with decreasing temperature, isolating families of fluorite-like phases that should be considered as definite compounds [59,118]. The most stable compounds have the compositions M2YF7 [57,119], M8R5F31, M = Ca, Sr [55,120] and M4Y3F17, M = Ba, Pb [56,78,121,122]. In MF2-YF3 systems, where M = Cd, Ca, Sr, high-temperature berthollide phases of variable composition with a LaF3– tysonite type structure are formed.
Optical properties of Sr<inf>2</inf>YF<inf>7</inf> material doped with Yb<sup>3+</sup>, Er<sup>3+</sup>, and Eu<sup>3+</sup> ions for solar cell application
2022, Journal of Alloys and CompoundsCitation Excerpt :Fig. 2a displays the low magnification TEM image of the SYF3@TiO2 sample to confirm a successful coating with TiO2. HRTEM image and diffraction pattern of SYF3@TiO2 (Fig. 2b) revealed that the measured lattice spacings are 3.28 Å and 3.5 Å corresponding to the (111) plane of SYF, and (101) plane of anatase TiO2, respectively [35–37]. Electron diffraction pattern of Sr2YF7 sample is also shown as an inset of Fig. 2b, where the interplanar distances were calculated to be 3.28, 2.85, 2.03, 1.72, 1.66, and 1.40 Å to assign to (111), (200), (220), (310), (222), and (400) lattice planes, respectively.
