dc.description.abstract	Flash evaporated amorphous Se_____Bi_(x = 0, 1, 2, 3, and 4 at.%) thin films of 350 پ} 10__ thickness have been investigated in the wavelength range of 200nm − 3000nm. It is found that the effect of increasing bismuth content on the as deposited films led to increased absorption coefficient, reflectance, refractive index and extinction coefficient while transmittance and optical band gap energy decreased. The Raman spectra showed peaks at 238.8____ ,248.3____, 249.5____, 250.7____, 251.9____, 488.1____, and 489.3____ due to selenium rings and chains at various bismuth concentrations.	en_US
