摘要：

Glasses with composition xLi(2)O-(40-x)Bi2O3-20CdO-40B(2)O(3) where (0 <= x <= 40) have been prepared using melt quench technique. Optical absorption spectra of the pure glasses reveled that the cutoff wave length decreases and optical band gap (E-opt) and Urbach energy (Delta E) increases with increase in Li2O content. The Eopt values of these glasses are found to be in the range 2.818-3.258 eV where as the values of.. are in the range 0.21-0.33 eV. Raman and infrared spectroscopies have been employed to investigate these glasses in order to obtain information about the competitive role of Bi2O3 and B2O3 in the formation of glass network. IR and Raman spectra show that these glasses are made up of [BO3], [BO4], [BiO3] and [BiO6] units. The formation of Cd in tetrahedral co-ordination was not observed.
