Silicate glasses with chemical composition in mol%: (75 mol% SiO2–15 mol% Na2O-10 mol% Ca2O) doped by different ratios (x) of AgNo3, (x = 0.0, 0.1, 0.5 and 1.0) were successfully prepared by melting method. Silver nanoparticles (AgNPs) have been precipitated in the prepared glasses via Nd:YAG nanosecond laser irradiation pulses. The A.C. conductivity behavior and the dielectric properties such as; (dielectric constant (e’) anddielectric loss (e”)), AC conductivity (σac’ and σac”), electric modulus (M’ and M”) and electric impedance (Z’ and Z”) have been investigated as a function of frequency for the prepared glass samples in the frequency range; from 0.1 Hz to 10 MHz at room temperature. The AC conductivity is proportional to AgNO3 and increased as silver nanoparticles concentrations inside the silicate glass matrix increasing.
