abstract = {This study investigates novel ZnO-doped
lithium-titanium-phosphate glasses, synthesized via the
melt-quenching method, and characterizes their physical,
structural, thermal, optical, chemical, mechanical, and
electrical properties, with a focus on the impact of varying
ZnO content on these properties. An increase in ZnO content
from 20 $mol\%$ to 27.27 $mol\%$ induces significant local
structural changes, promoting enhanced network
polymerization, density, and chemical durability, while
concurrently reducing thermal stability and mechanical
strength. EPR analysis confirmed that titanium remained in
the Ti4+ state, while optical measurements revealed an
increased band gap, attributed to the role of ZnO in
preventing Ti4+ reduction and minimizing localized states.
The electrical conductivity decreases with increasing ZnO
content, with the highest value measured at 1.73 × 10-10
Ω-1 cm-1. High-ZnO glasses exhibit mainly electronic
conductivity of 4.02 × 10-9 Ω-1 cm-1 at room temperature.
The frequency-dependent conductivity follows Jonscher's
power law, with the charge transport governed by a
correlated barrier-hopping mechanism, remaining stable
across temperatures and compositions.},
