Role of Sm+3 ions on structural, optical and radiation shielding properties of lead borosilicate glasses

Abstract lead borosilicate glasses comprising samarium oxide (Sm2O3) had been developed by using melt-quenching procedure. The values of glass density became reported to enhance as Sm2O3 raise from 3.632 g/cm3 for 1 percent Sm2O3 to 3.764 g/cm3 for 6 percent Sm2O3, were attributable to the substitution of boron with lower density by samarium with higher density. The molar volume of the samples prepared was calculated from the density data. Optical absorption spectra have been reported and optical parameter values like the optical transformation, optical electronegative behavior, index of refraction, high frequency constant of dielectric, singular oscillator energy and dispersive energy have been calculated. The optical parameters were associated with the Sm2O3 ratio. Judd–Official concept has been extended to the glass absorption spectra to the model of radiative and laser properties. Judd–Official parameters (Ω2, Ω4, Ω6) were defined as Ω2 > Ω4 > Ω6 and linked to the composition of glass. Such glasses have been realized to be used as photonic devices. The maximum & least MAC values were obtained at the energies of 15 keV & 6 MeV for all Sm-Glasses. The trend of the LAC values follows the trend: (LAC)Sm1
