RAMAN CHARACTERIZATION OF CuCr2-xSnxS4 SPINELS

ABSTRACT Polycrystalline thiospinels CuCr2-xSnxS4 (x = 0.4, 0.8, 1.0 and 1.4) were synthesized via conventional solid-state reaction. The samples were characterized by powder X-ray diffraction (XRD), energy-dispersive X-ray analysis (SEM-EDS) and Raman spectroscopy. All the samples were indexed in t...
