windows, because they may be used as layers for optical and opto-electronic devices, etc. [21–29]. These glasses have a long infrared (IR) cutoff, which makes them ideal candidates for optical transmission [30]. Bismuthate glasses containing alkali oxide act as ionic conductors and possess high conductivity compared to other heavy metal glasses [31,32]. However, the study of the physical properties of ionic glasses has been paid little attention. Recent studies by IR, UV–VIS, and Raman spectroscopy on binary lithium bismuthate and alkaline earth containing ternary lithium bismuthate glasses revealed the presence of distorted BiO6 polyhedra as the main structural unit in these glasses
