Polymers are commonly utilized sophisticated materials that may be found in nearly every item we use daily. Polymers' relevance has recently been highlighted due to their applications in several fields of science, technology, and industry, ranging from fundamental usage to biopolymers and medicinal polymers. The research aims to study the effect of annealing with irradiation on the optical properties of PMMA films used in many industrial and medical applications. Where UV-Vis spectroscopy was used to study the absorption and emission spectra in calculating the optical parameters, it was found that the optical energy gap of the indirect transmission type decreases with the increase in the thickness of the thin films. Also, the optical parameters such as the absorption coefficient, refractive index, attenuation coefficient, and dielectric constants increase with increasing thickness. The character of FTIR spectra and the locations of the bands have been demonstrated to change with different time annealing temperatures with irradiation. Irradiation has been demonstrated to change the shape of FTIR Spectra and the placement of the peaks. [ABSTRACT FROM AUTHOR]
