Fabrications a new family of samarium lead phosphate glasses, determination electrical, structural and optical properties under effect of different gamma doses

Abstract

Structural, optical and electrical properties of developed (P2O5)47-(Na2O)23-(Al2O3)6-PbO(24−x)-(Sm2O3)x (where x = 0.5, 1 and 3 mol%) at different gamma irradiation doses (0, 10, 50 KGy) have been investigated. Melt-quenching method was used for synthesizing these glasses. XRD observations provide for the ampophosity of the as-prepared glasses. The effect of different gamma irradiation doses and Sm2O3 contents affect crystallinity of the developed samples. Moreover, the results show a decreasing in the transmittance light as the gamma doses increase from 0 to 50 kGy. The both calculated direct and indirect optical band gap were found to be affected by gamma irradiation doses for (P2O5)47-(Na2O)23-(Al2O3)6-PbO(24−x)-(Sm2O3)x. On the other hand, the electrical activation energy and electrical conductivity of the glasses were affected by gamma irradiation doses for (P2O5)47-(Na2O)23-(Al2O3)6-PbO(24−x)-(Sm2O3)x (where x = 0.5, 1 and 3 mol%). These various studies forces to fabricate a glass material that could be utilized to attenuate or reduce gamma-radiation.
