✦ Synopsis

In this work, we report the optical properties of bulk Se 93ÀX Zn 2 Te 5 In X (X ¼ 0, 2, 4, 6 and 10) chalcogenide glasses. Refractive index, extinction coefficient, real dielectric constant (e 0 ), imaginary dielectric constant (e 00 ), absorption coefficient (a) and energy band gap were obtained from analysis of common range (250-1100 nm) UV/Visible transmittance spectrum. Besides, transmission percentages were obtained from FTIR spectra in wave number range 4000-400 cm À1 .The concentration dependence structural phenomena have been explained with help of average coordination /zS.
