Abstract

The impact of irradiation by gamma rays with different doses on optical properties of polystyrene/Rhodamine 6G films was examined. FTIR spectrum revealed the absence or no occurrence of the interaction between gamma rays and PS/Rh6G films, which makes them chemically stable. The PS/Rh6G optical properties UV-VIS were assessed in the 200-900 nm wavelength range. Experimental research has demonstrated that increasing the gamma radiation energy improves the PS/Rh6G film's absorbance, absorption coefficient, imaginary and real dielectric constant, refractive index, extinction coefficient, and refractive index. With an increase in irradiation, PS/Rh6G films transmittance and energy band gap diminish..
