Crystal Structure Analysis of Sr2MgSi2O7 Doped with Eu2+ and Dy3+ using Rietveld Refinement

Sandip Kumar Shrivastava

Abstract: This study examines the crystal structure of Sr2MgSi2O7 doped with Eu2+ and Dy3+ using the Rietveld refinement method. The phosphor was synthesized via solid-state reaction and characterized using X-ray diffraction XRD. The observed XRD patterns matched the crystallographic database, confirming the structure. Rietveld refinement revealed the impact of doping on lattice parameters, with a slight increase in cell volume. The refinement showed good convergence, highlighting the methods effectiveness in studying luminescent materials.
