Optical and radiation shielding properties for novel glass material: TeO2/Nb2O5/Ta2O5/La2O3

Glass samples with (86-x)TeO2 – 12Nb2O5- x(Ta2O5) -1.0La2O3 where ???? = 1.0 (glass TNTL1), 5.0 (glass TNTL2), 8.0 (glass TNTL3), and 10 (glass TNTL4) mol% composition were synthesized by a melt quenching technique. The gammaray attenuation parameters of TNTL system such as MAC, LAC, HVL, MFP, Zeff, and Neff were analyzed in this study in order to better understand the effect of Ta2O5 on photon absorption.Within the 190-2500-nm wavelength range, the optical properties of prepared TNTL glasses were also evaluated. It was observed from the optical absorption spectra that all glass samples studied had good optical transparency. The findings indicated that adding Ta2O5 to glass enhances the gamma protection ability as well as the optical properties. The densities of the samples ranged from 5.66 to 6.49 g/cm3, depending on the Ta2O5 concentration. Sample TNTL4 had the best preformace, according to the results recorded.
