Abstract(summary):

This study explores a series of optical, thermal, and structural properties based on 60P₂O₅–30ZnO–10Al₂O₃ (60P) glasses that doped with varied rare earth (RE) elements Yb₂O₃ and P₂O₅ components replaced by SiO₂. It was found that the glasses density decrease with SiO₂ concentration added to replace P₂O₅, whereas they increase with increased concentration of Yb³⁺-doped. Moreover, the glasses transition temperature, softening temperature, and refractive index increase with Yb³⁺ concentrations added, whereas the thermal expansion coefficient decreases. For the 60P glasses, 7 mol%Yb₂O₃ doped has the maximum fluorescence which is suppressed when Yb₂O₃ is doped up to 9 mol%. In addition, maximum lifetime was found to be 2.68 ms at an optimal Yb³⁺-doping at 1 mol%for 53P₂O₅–7SiO₂–30ZnO–10Al₂O₃ glass.
