Transparent titanium ions doped lead-borate glasses with optimized persistent optical features for optoelectronic applications

The detection of distinctive optical materials is still under investigation. Hence, here, the melt-quenching approach was used to create a series of PbO–B2O3–TiO2 (PBT) glass materials with improved optical features. The transmittance of this PBT glass system decreased, and its reflectivity increased, through titanium ions doping. Spectrophotometric studies show that the optical bandgap energy of the PBT glasses decreased from 2.60 eV to 2.44 eV, arising from the permitted indirect electronic transitions, whereas the Urbach energy augmented from 0.029 eV to 0.042 eV as the TiO2 content increased. The incorporation of titanium ions into the lead-borate glass improved the behavior of the optical parameters, optical constants, energy loss factor, and dispersion parameters, as well as controlling the sheet resistance, coverage density, figure of merit, and plasma resonance frequency. Additionally, the electronic
