Correlation between optical and shielding properties of phosphate glasses with alkaline oxide and their application

Abstract

In numerous tissue engineering and dental applications, bioactive glasses are utilized. These glasses have unique characteristics that make them attractive candidates for a variety of applications. A new bioactive glass system with the structure of 45P2O5 − 20CaO − 15CaCL2 − 8KF − (10 − x) Li2O − (x) TiO2 was developed in this study, with x = 2, 6, and 8 mol%. For usage in radiation protective applications, it was evaluated. By using an ultraviolet–visible spectrophotometer, we were able to measure the absorbance (Abs) and transmittance (T %) in the range of wavelengths 190–2500 nm. Furthermore, the optical energy gap of the produced glasses was determined. Using the MIKE software, the mass attenuation coefficients (MAC) of the bioactive glasses under investigation were calculated for energies ranging from 15 to 200 keV. The 𝐿𝐿𝐿𝐿𝐿𝐿, 𝑍𝑍𝑒𝑒𝑒𝑒𝑒𝑒, 𝑁𝑁𝑒𝑒𝑒𝑒𝑒𝑒, 𝐻𝐻𝐻𝐻𝐻𝐻, 𝑇𝑇𝑇𝑇𝑇𝑇, 𝑎𝑎𝑎𝑎𝑎𝑎 𝑀𝑀𝑀𝑀𝑀𝑀 (Linear attenuation coefficient, effective atomic number, effective electron density, half value layer, tenth value layer, and mean free path) of the bioactive glasses were calculated. According to the findings, the addition of titanium dioxide (TiO2) as well as the metal oxide such as Li2O to bioactive glasses generates significant differences in the attenuation characteristics of bioactive glasses. The results indicate that the PCKLT3( 𝑇𝑇𝑇𝑇𝑇𝑇2= 8mol%) bioactive-glass sample had the best attenuation among other samples.
