Therefore, the physical properties of such glasses exhibit discontinuous changes when the structural role of the cation switches over in this way [5]. Also, glasses containing
Bi2O3 have attracted a considerable attention because of their wide applications in the field of glass-ceramics,
thermal and mechanical sensors, reflecting windows, radiation shielding and because they may be used as layers for
optical and opto-electronic devices, etc. [6] These glasses have a long infrared (IR) cut-off, which makes them ideal
candidates for optical transmission [7]. Bismuthate glasses containing alkali oxide act as ionic conductors and
possess high conductivity compared to other heavy metal glasses [8]. However, the study of the physical properties
of the ionic glasses has been paid little attention.
