Glassesin  the  series  30MgSO4-(70-x)  P2O5-xSm2O3 0.2 ≤x≤1.0  mol  percentwere  prepared  by  single  step melt-quenchtechniques,   thestructure,   physicalandoptical propertiesofsamarium   oxide   at   different concentrationswere   studied.The   amorphous phase   of   the   samples   was   verifiedby   X-ray   diffraction spectroscopy,  the  structural  units  were  investigated  using  Fourier Transform  Infrared, Raman  and  NMR spectroscopy where the spectra revealthe presence of symmetric, asymmetric, torsoionalandbending vibration of phosphate groups,the NMR spectra reveals the changes in Qndistributionhere discussed,thecompositional dependenceonphysical (density,  average  molar  weight,dielectric  constant,Inter-nuclear  distance, Field strength,Molar volume, Molar refractivity  etc) and optical  parameterswere determined. In  terms  of  structural modifications, there  is variation of density and molar volume, t.....
