Glasses of compositions of 20Li20 • xBi2O3• (79-x)B2O3 + (1.0 mol%) CuFe2O4, with 0 ≤ x ≤ 40 were prepared by melt-quench technique. To obtain the glass–ceramics the controlled heat treatment were given to the prepared glasses. Two nano crystalline phases, i.e., Li2B4O7 and LiB3O5 were observed from X-ray diffraction patterns of the prepared glass– ceramic samples. We investigated the change in coordination number of network formers B2O3 and Bi2O3 and network modifiers Bi2O3, Li2O and CuFe2O4. Crystallites size (lies in range ∼47-50nm) and lattice strain (ε) were calculated for major phases for all prepared samples. FT-IR study revealed the de-polymerization of borate groups that change with heat treatment and Bi2O3 content. Deconvolution of IR absorption spectra resolves the overlapped and hidden peaks in IR spectra. Sharp and more intense FTIR peaks confirm the vibrations due to crystallites Li2B4O7 and LiB3O5 and change in coordination of network forming borate units.
