A simplified study on physical and mechano-structural properties of newly produced Sm3+ doped zinc telluro-phosho-borate glasses

To unveiled the function of exchanging Sm2O3 for B2O3 on the physical and mechanostructural traits of multi-component glass, five distinct type (A, B, C, D and E) of glasses originated from (50-x)B2O3-10P2O5-30TeO2-10ZnO-xSm2O3 (0.1≤x≤1.5, mol%) compositions were fabricated by using ordinary approach of melt-quenching. The noncrystallinity status of the synthesized samples was established by X-ray diffraction (XRD) profile. However, with sequential replacement of B2O3 by Sm2O3, the deduced values of physical entities such as density (𝑑𝑑𝑠𝑠), Sm3+ ions concentration (𝑁𝑁𝑖𝑖), field strength (F) and glass hardness (𝐻𝐻𝑉𝑉) of our produced glasses were significantly amplified, while the molar volume (𝑉𝑉𝑚𝑚) alongside polaron radius (𝑟𝑟𝑝𝑝) and inter-nuclear distance (𝑟𝑟𝑖𝑖) decline. Besides, data from FTIR with consequential deconvoluted spectral showcased the presence of BO3, BO4, TeO3, TeO4 and PO4 functional groups which were randomly distributed within the main glass network.
