Rietveld refinement of the doped lanthanum fluoride (EuLaF₃) lattice


Doped and pure lanthanum fluoride (LaF₃) is an important material that finds applications in electrodes, fluorescent lamps, fiber optics and radiation applications. Europium doped LaF₃ is also used as an ion-specific fluoride detecting electrode in solutions.


These applications may require a careful study of unit cell of this material for a very specific application. Figure 1 and 2 show the Rietveld refinement and results of the refinement of Eu doped LaF₃ material using the data collected on Rigaku's Ultima IV multipurpose diffraction system.
