Optical properties for sete thin films

Abstract EN

Chalcogenide glasses SeTe have been prepared from the high purity constituent elements .Thin films of SeTe compound have been deposited by thermal evaporation onto glass substrates for different values of film thickness .

The effect of varying thickness on the value of the optical gap is reported .

The resultant films were in amorphous nature .

The transmittance spectra was measured for that films in the wavelength range (400-1100) nm .

The energy gap for such films was determined.
