Abstract

Glass containing zinc-lead boroselenate glasses with the formula 10ZnO–20PbO₂-xB₂O₃–(70 − x)SeO₂ (where 10 ≤ x ≤ 60 mol%) were prepared using the conventional melt quenching method. Several physical properties, including density and molar volume, were determined. Glass transition temperature (T_g) was investigated using differential scanning calorimetry (DSC), revealing a decrease in T_g from 347 to 426 °C as the B₂O₃ content increased. Optical absorption studies showed that as the SeO₂ content decreased, the cutoff wavelength increased while the optical band gap energy (\({E}_{opt}\)) and Urbach energy (\({\Delta E}\)) decreased. The \({E}_{opt}\) values for these glasses ranged from 2.699 to 2.091 eV, while ΔE values fell between 0.232 and 0.351 eV. FTIR measurements revealed that SeO₃ tetragonal and SeO₄ pyramidal units, as well as BO₃ and BO₄ units, were present in the network structure of these glasses. Additionally, Raman spectra identified distinct structural units. The FTIR and Raman spectra did not show any specific SeO₂ absorption bands. However, the presence of SeO₂ in the glass matrix changed how PbO₂, ZnO, and B₂O₃ were absorbed.

B2O3对硒酸锌铅玻璃物理、热、光学和结构性能的影响

含硼硒酸锌铅玻璃的分子式为10ZnO-20PbO2-xB2O3 -(70−x)SeO2(其中10≤x≤60 mol%) were prepared using the conventional melt quenching method. Several physical properties, including density and molar volume, were determined. Glass transition temperature (Tg) was investigated using differential scanning calorimetry (DSC), revealing a decrease in Tg from 347 to 426 °C as the B2O3 content increased. Optical absorption studies showed that as the SeO2 content decreased, the cutoff wavelength increased while the optical band gap energy (\({E}_{opt}\)) and Urbach energy (\({\Delta E}\)) decreased. The \({E}_{opt}\) values for these glasses ranged from 2.699 to 2.091 eV, while ΔE values fell between 0.232 and 0.351 eV. FTIR measurements revealed that SeO3 tetragonal and SeO4 pyramidal units, as well as BO3 and BO4 units, were present in the network structure of these glasses. Additionally, Raman spectra identified distinct structural units. The FTIR and Raman spectra did not show any specific SeO2 absorption bands. However, the presence of SeO2 in the glass matrix changed how PbO2, ZnO, and B2O3 were absorbed.
