Unveiling the structural, optical, and electromagnetic attenuation characteristics of B2O3–SiO2–CaO–Bi2O3 glasses with varied WO3 content.

This study provides insight into B 2 O 3 –SiO 2 –CaO–Bi 2 O 3 glasses where novel results for the effects of WO 3 content on its structural and optical properties have been demonstrated. Thus, provides useful data for developing new glasses for optical and electromagnetic shielding applications. The effect of WO 3 content on the structural and optical properties of B 2 O 3 –SiO 2 –CaO–Bi 2 O 3 glasses was investigated along with radiation shielding features which have been calculated by XCOM program. BSCB/W-00, BSCB/W-2.5, BSCB/W-5.0, BSCB/W-7.5, BSCB/W-10, BSCB/W-15, and BSCB/W-20 refer to seven samples of bismuth borosilicate glass system doped with 0.0, 2.5, 5, 7.5, 10, 15, and 20% of WO 3 , respectively, synthesized using the melt quenching technique. The density of the glasses decreased with increasing WO 3 content due to the replacement of Bi 2 O 3 with lower-density WO 3. It was found that the absorption coefficient decreased with increasing WO 3 content up to 10 wt%, but showed an opposite trend for samples with higher WO 3 content. The optical band gap and the transition type were affected as the WO 3 content increased. The electromagnetic wave decay or skin depth was also calculated. Overall, the shielding effectiveness of investigated samples BSCB/W-00, BSCB/W-2.5, BSCB/W-5.0, BSCB/W-7.5, BSCB/W-10, BSCB/W-15, and BSCB/W-20 has reduced with the enlargement of the WO 3 concentration. BSCB/W-00, out of all the samples tested, has the highest shielding efficiency. • WO 3 -doped BSCB glasses show novel optical/structural traits. • WO 3 addition alters properties, enhancing optics/radiation shielding use. • Glasses display polycrystalline or amorphous structures based on WO 3 level. • Tunable band gap properties make them apt for optoelectronics. • Study aids in developing tailored glasses for radiation protection.
