Effect of Chromium Doping on the Structural Properties of Strontium Fluoride Compound

Abstract

SrF2: Cr (x = 0.00-0.1-0.15-0.2-0.25-0.3-0.35 wt%) powder has been successfully prepared using the solid-state reaction method. The phosphors were characterized by differential thermal analysis (DTA), X-ray diffraction (XRD). The samples were annealed at 750℃/6h. The structural properties of strontium fluoride samples doped with different Cr ratios were investigated. The results of the X-ray diffraction patterns showed that the samples are polycrystalline structure in the cubic phase and show the presence of (111), (020), (022), (131), (222), (040) levels in the pure SrF2 sample and the preferred orientation is (111) for pure SrF2. The distance between the crystal planes (d), the crystal size (D), and the lattice constant (a) were determined.Keywords: powder, SrF2, solid state reaction, Structural properties, DTA, XRD DOI: 10.7176/CMR/16-1-01Publication date: January 31st 2024
