A comparative study on optical properties of Se–Zn–In and Se–Zn–Te–In chalcogenide glasses

In contemporary world optoelectronics materials are used in daily life owing to its verity of applications. Utility of these materials makes them attractive for investigations. Specifically study regarding optical properties of recent developed materials is worth for technical uses. Therefore, this work demonstrates a comparative study of extinction coefficient (K), real dielectric (ɛ′) and imaginary dielectric (ɛ′′) constants, refractive index (n) and optical energy band gap (Eg) with structural unit for Se98–xZn2Inx (0 ≤ XIn ≤ 10) and Se93–yZn2Te5Iny (0 ≤ YIn ≤ 10) chalcogenide glasses. Fixed amount of Te with increasing In concentration as cost of Se is largely influence the optical parameters of the materials. Values of optical parameters are obtained higher and lower respectively at thresholds structural units values. This comparative study demonstrates that enhanced values of optical parameters have been obtained for Te containing Se–Zn–In glasses.
