| dc.description.abstract | This paper reports the influence of bismuth (Bi) addition on the optical properties of thin films of Se85-xTe15Bix (x = 0, 1, 2, 3, 4, 5) chalcogenide glassy alloys. This has been done by analyzing the transmission spectra, measured at normal incidence, in the spectral range 400 to 1500 nm. Optical band gap (Eg) is estimated using Tauc’s extrapolation and is found to decrease from 1.46 to 1.24 eV with the Bi addition. This behavior of optical band gap is interpreted in terms of electronegativity difference of the atoms involved and cohesive energy of the system. | en_US |
