dc.description.abstract	The objective of this study is to investigate the effect of WO3 doping on optical and shielding properties of TeO2B2O3 glass system. A new glass series of [(TeO2)(0.7)(B2O3)(0.3)(ZnO)(0.3)](1-x)(WO3)(x) had been synthesized through l melt-quenching method. Structurally, all glass samples are in long-range structural disorder which has an amorphic nature. The density of samples was seen to decrease as the concentration of WO3 and molar volume increases. In optical analysis, the values for direct and indirect optical band gaps were varied between 2.37 and 3.12 eV and between 2.27 and 2.58 eV respectively. The values of Urbach energy were found to lie within 0.35-1.33 eV. For radiation shielding features, linear attenuation coefficients obtained with FLUKA code and XCOM database are found to be in good harmony with relative difference < 3%. Based upon mean free path, half value layer and linear attenuation coefficient, the glass sample ZnOB2O3TeO2WO3(0.00) having highest per-centage of TeO2 is found to be the most excellent shielding composition among the samples investigated in this study.
