New bismuth boro-tellurite glass within the compositions 20Bi(2)O(3)-25B(2)O(3)-(55-x) TeO2-x TiO2 (0 <= x <= 10 mol%) have been prepared by normal melt quenching technique. The structure of the glass and then the glass-ceramic was investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and the transmission electron microscopy (TEM). The differential scanning calorimetry (DSC) measurements were carried out on the prepared glass samples to estimate their thermal behavior. Selected glass samples were heat treated at different annealing temperatures and times above the glass transition temperature. The optical absorption spectra were measured in the spectral range (380-600 nm) at room temperature. The Fourier transform infrared (FTIR) absorption spectra of all glasses were in the range (350-4000 cm(-1)) have been recorded and designated.
