| Abstract | ||
| The optical properties of polymer composite polycarbonate-polystyrene (PC-PS) films prepared by casting technique were studied in the visible and ultraviolent wavelength regions. It was found that the optical absorption is due to direct allowed transitions for pure and composite polymer films, while the energy gaps and the width of the tail localized states of the composite was lied in the mid values of the pure samples. The optical constants refractive index , extinction coefficient , the real and the imaginary parts of the dielectric constant have been also calculated. The dielectric constant and refractive index become more stable for composite sample. | ||
