Abstract This comprehensive study investigates the influence of silver oxide (Ag₂O) doping on the dielectric properties and spectroscopic characteristics of lithium niobate phosphate glass systems (Li₂O―Nb₂O₅―P₂O₅). Glass samples with compositions 35Li₂O-5Nb₂O₅-(60-x)P₂O₅-xAg₂O, where x ranges from 0.5 to 2.5 mol%, were prepared using the conventional melt-quenching technique. Structural characterization was performed using infrared (IR) spectroscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS), revealing significant polymerization of the glass network at optimal Ag₂O concentrations. Optical absorption and photoluminescence studies demonstrated surface plasmon resonance (SPR) effects arising from Ag⁰-Ag⁺ clusters formation within the glass matrix. Dielectric measurements across frequency ranges (0.01 Hz–1 MHz) and temperatures (303–513 K) showed enhanced dielectric constants at higher Ag₂O content, attributed to increased space charge polarization. The transition from polaron to ionic conduction mechanisms was observed at approximately 1.0 mol% Ag₂O concentration. These findings suggest that Ag₂O-doped lithium niobate phosphate glasses exhibit promising characteristics for applications in solid-state electrolytes and energy storage devices.
