Abstract:

 The present paper deals with prepared of ternary Se80-xTe20Gex system alloys and thin films. The XRD analysis improved that the amorphous structure of alloys and thin films for ternary Se80-xTe20Gex (at x=10and 20at.%Ge) which prepared by thermal evaporation techniques with thickness 250 nm. The optical energy gap measurements show that the optical energy gap decreases with increasing of (Ge) content from (1.7 to 1.47 eV)It is found that the optical constants, such as refractiveindex ,extinction coefficient, real and imaginary dielectricconstant are non systematic with increasing of Ge contentsand annealing temperatures.
