Glasses of the composition xPr{sub 6}O{sub 11}- (35-x)TeO{sub 2}-65B{sub 2}O{sub 3} (x=0, 0.1 to 0.5 mol %) have been prepared using the melt quenching method. The ac and dc conductivity of glass have been measured over a wide range of frequencies and temperatures. Experimental results indicate that the ac conductivity depend on temperature, frequency and Praseodymium content. The conductivity as a function of frequency exhibited two components: dc conductivity (σ{sub dc}), and ac conductivity (σ{sub ac}). The activation energies are estimated and found to be decreases with composition. The impedance plot at each temperature appeared as a semicircle passes through the origin.
