The glass density increases noticeably (from 6020 for BaTiO₃ to 2533 kg/m³ for SiO₂), and the molar volume decreases, suggesting a denser and more compact structural arrangement. The mechanical properties exhibited a notable improvement upon the addition of BaTiO₃. Specifically, the longitudinal ultrasonic velocity (<i>V</i>_<i>L</i>) increased from 3927 to 4458 m/s, and the shear velocity (<i>V</i>_<i>S</i>) increased from 2317 to 2630 m/s, indicating a reinforced glass network. The bulk modulus increased from 35.71 to 58.06 GPa, and Young’s modulus increased from 57.2 to 92.98 GPa. These significant increases in elastic moduli were attributed to tighter atom packing and higher levels of cross-linking within the glass matrix. Furthermore, the glass structure’s increased rigidity and connectedness were further indicated by the Debye temperature (<i>θ</i>_<i>D</i>), which increased from 296.8 to 347.3 K. The influence of BaTiO₃ on the thermal analysis is demonstrated, which revealed that increasing BaTiO₃ content raises both the glass transition and crystallization temperatures.

Structural characterization via XRD and profilometry indicated an increase in film thickness with higher deposited charges. The analysis revealed a decrease in strain and Urbach energy, indicative of reduced structural defects and an increase in the bandgap. SEM images illustrated the porous nature of the film surfaces, with elongated 2D structures enhancing light absorption through multiple reflectance effects. However, increased charge deposition led to particle agglomeration, reducing light absorption efficiency and active surface area, thus diminishing photogenerated charge generation. Electrochemical and photoelectrochemical characterization confirmed the n-type nature of all films, with carrier concentration increasing with film thickness. Nevertheless, the thinnest film (50 mC) exhibited the highest photocurrent, attributed to reduced particle agglomeration, enhanced light absorption, greater charge transport capacity, and superior electrocatalytic behavior, thereby minimizing recombination effects.
