Description
Summary:98[20Li 2 O- x Bi 2 O 3 -(80- x )TeO 2 ]-2Ag glass system has been prepared using a melt-quenching method and characterized by impedance spectroscopy and optical absorption to study the effect of Bi 2 O 3 substitution on DC conductivity and nonlinear optical properties of the glass samples. The nonlinear behavior of DC conductivity σ DC showed an initial increase in σ DC for x ≤ 5 mol% before a large drop at x  = 7 mol% due to blocking on Li + ionic conduction which may be associated with mixed ionic–electronic (MIE) effect. The anomalous behavior of nonlinear refractive indices n 2 and optical susceptibility χ 3 with Bi 2 O 3 substitution showed an initial increase at x   7 mol%. The minimum in n 2 and χ 3 were suggested to be due to the MIE effect that contributes to a reduction in polarization. On the other hand, optical basicity Λ initially increased for x
