The structural characteristics of glass samples are examined using XRD. This glass's molar volume decreased from 18.21 to 17.46 (cm3/mol), while its density increased from 3.213 to 5.967 g/cm3. Differential thermal analysis data were used to assess the thermal stability (Delta T) for BSLa samples. It was discovered that when the La2O3 amount increased, the glass stability increased. The optical band gap (Ediopt), (Eindi opt ) and Urbach's energy (Eu) were computed using UV absorption spectra. (Ediopt) decrease from 4.323 to 3.816 eV and (Eindiopt) decrease from 3.413 to 2.95 eV, whereas (Eu) increase from 0.278 to 0.324 as a result of the changes of borosilicate's structured caused by the addition of La2O3. The examined glasses may be utilized for non -linear optical applications, according to the high (n) and low metallization (M) values. The Phy-X tool was utilized to obtain (MAC), (LAC), and (Zeff) of the suggested glasses within the energies 0.015-15 MeV. The BSLa16 sample achieved the highest values of the (MAC), (LAC), and (Zeff). Consequently, BSLa16 is a good option for gamma-ray shielding applications.eninfo:eu-repo/semantics/closedAccessDtaOpticsShielding CharacteristicsArticle150WOS:0012143012000012-s2.0-85189092497N/A10.1016/j.optmat.2024.115298Q1
