Seductive and impressive applications of samarium oxide based materials in semiconductor science, created
an interest to synthesize and study their physical properties. Therefore, after preparing pure samarium oxide
and graphene/samarium oxide powders through hydrothermal technique; with use of X-Ray diffraction (XRD),
field emission scanning electron microscopy (FESEM), Fourier transform infrared spectroscopy (FTIR), Raman
spectroscopy, and UV-Visible spectrophotometry; structural, optical, and morphological properties of the
samples have been evaluated. Using XRD, lattice constants and some related structural parameters were determined.
Variation of optical band gap has been calculated too, with aiding absorbance, The XRD data revealed
prevailed cubic samarium oxide phase in both samples, even though a sharp diffraction peak of graphene was
attended in graphene/samarium oxide sample. SEM, Raman, and FTIR analysis showed the effects of graphene
addition on main lattice of samarium oxide. Furthermore, the decrease of optical band gap due to graphene
was also notable.
