Abstract
Binary (1â¯ââ¯x)(TeO2)â¯ââ¯x(PbO), xâ¯=â¯0, 0.10, 0.15, 0.20, 0.25, 0.30â¯mol% glass system was fabricated using melt quenching method. X-ray diffraction (XRD) technique was employed to confirm the amorphous nature. The microanalysis of the major components was performed using energy dispersive EDX and X-ray spectrometry. Both the molar volume and the density were measured. FTIR and UV spectra were recorded at 400-4000â¯cm-1 and 220-800â¯nm, respectively. The optical band gap (Eopt), Urbach's energy (Eu), index of refraction (n) were calculated using absorption spectrum fitting (ASF) and derivation of absorption spectrum fitting (DASF) methods. Molar refraction Rm and molecular polarizability αm have been calculated according to (ASF) method.
