Abstract
We have studied the effect of Al2O3 dopant on the optical properties of a polymer polystyrene. Pure and Al2O3 doped polystyrene samples were prepared using the hot press method. The adding percentages of Al 2O3 in the prepared samples were (0, 20, 40, 50, 60) wt%. The thickness of the samples were measured by using indicating micrometer and ranged (1.2 - 1.4) mm. Transmission and absorption spectra have been recorded in order to study the effect of increasing Al2O3 percentage on the optical parameters such as absorbance, transmittance, absorption coefficient, refractive index, extinction coefficient, and, real and imaginary parts of dielectric constant. This study reveals that all these parameters affect by increasing Al2O3 percentage.
