In this work, copper (Cu)-doped titanium dioxide (TiO2) nanoparticles were prepared by co-precipitation. For studying the morphological properties, the copper doped titanium dioxide (TiO2:Cu) nanocrystalline structures were characterised through powder X-ray diffraction and field emission scanning electron microscopy. The prepared TiO2:Cu nanoparticles were annealed at two temperatures, namely, copper doped titanium dioxide annealed at 723 K temperayure (TC1) and copper doped titanium dioxide annealed at 1073 K temperayure (TC2).

Motivated by our previous study on Sm ions as thermoluminescence (TL) sensitizers to the BaO-ZnO-LiF-B O -Yb O glass system, in the current study we examined the effect of Er ion co-doping on the TL characteristics of this glass system. The 4f-4f electronic transitions of the Er and Yb ions were confirmed via the optical absorption spectrum. Notably, the use of Yb -Er ions failed to improve the TL intensity, sensitivity, and trap density.

We analyzed the mechanical properties and radiation-shielding performance of a lithium zinc bismuth silicate glass system. The composition of these glasses is 20ZnO-30LiO-(50-x)SiO-xBiO (x varies between 10 and 40 mol%). The mechanical properties of the investigated glass system, such as Young's modulus (), bulk modulus (), shear modulus (), and longitudinal modulus (), were determined using the Makishima-Mackenzie model.
