Abstract

Thin film of chalcogenide glassy alloy Se90In9.3Cu0.7 was deposited glass on substrate at room temperature (300k) by thermal evaporation technique. The refractive index(n) is determined by using the optical transmission spectrum. The absorption coefficient (?) and the refractive index (n) are determined from the reflectivity and transitivity spectrum in the range of 500-2500nm.The dielectric behavior is discussed by calculating and drawing the real (?r) and the imaginary (?i) parts of the dielectric constant versus the photon energy (h?). The oscillator energy (Eo), dispersion energy (Ed) and other parameters are determined.
