摘要：
In this work, we report the optical properties of bulk Se93-XZn2Te5InX (X = 0, 2, 4, 6 and 10) chalcogerride glasses. Refractive index, extinction coefficient, real dielectric constant (E), imaginary dielectric constant (epsilon ''), 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(-1). The concentration dependence structural phenomena have been explained with help of average coordination < z >. (C) 2009 Elsevier B.V. All rights reserved.
