摘要: Abstract Bismuth based glasses containing LiF, Li2O and SrO were investigated by different physical, spectroscopic transport techniques. The results show that density of the glass system increases whereas transition temperature decreases with increase in LiF content. decrease is attributed to entry fluoride ions into network mainly substitutionally place oxygen ion. dc electrical conductivity present fluorine due mixed contribution positively charged lithium cations throughout negatively fluorine, which may act as impurity and/or terminal non-bridging halide Infrared Raman indicate consists BiO6 octahedral BiO3 pyramidal units.
