Thermal and radiation shielding characteristics of erbium ions doped zinc tellurite glasses.

Tellurium, zinc, and erbium oxides glasses are made using the melt-quenching technique. The XRD results show that the glass samples are naturally amorphous. The TeO 4 units' extended vibration are performed using FTIR. On the other hand, the TeO 3 as well as Er 2 O 3 are detected using deconvolution. When the concentration of erbium ions increases, the density and molar volume will also increase. The high value of thermal diffusivity at 0.02 and 0.03 M fractions, a large value of glass stability (greater than 100 °C), and strong thermal stability are excellent for fibre drawing. As a result, the highest linear attenuation coefficient (LAC) values are found for the sample with 5 mol% Er 2 O 3 content, where the values drop suddenly from 0.95744 to 0.21065 cm−1 over the tested energy which ranges between 0.284 and 2.51 MeV. Among the TZEr samples, TZEr 5 has the lowest half-value layer (HVL) values ranging from 0.00243 to 0.08252 cm. Thus, both LAC and HVL are considered as suitable options for radiation shielding materials. [ABSTRACT FROM AUTHOR]
