Abstract
Gold nanoparticles have been synthesized in a base glass with composition 30Li2O‐70B2O3 using gold chloride (HAuCl4.3H2O) as a dopant. The samples are characterized using XRD, ESR, SEM and optical absorption in the visible range. AC conductivity studies have been performed at RT over a frequency range 100 to 10 MHz. The dc conductivity is calculated from the complex impedence plot. The dc conductivity is found to be increasing with the increase of dopant concentration. AC conductivity data is fitted with Almond‐West law with power exponent ‘s’. The values of ‘s’ is found to lie in the range of 0.70–0.73.
