تاثير التشويب على الثوابت البصرية لأغشية البولي مثيل ميثاكريلات (PMMA) المشوبة بمادة الفينول فثالين(phph)

Abstract

In this research, The effect of dopping on the optical constants of (PMMA) dopping with phenolphthalein(8%)was studied. films were prepared by using casting technique with thickness(20μm), Optical properties for this films were studied by recording the Absorption and Transmission spectra in the wavelength rang (190-1100)nm. And then the absorption, Transmission, the reflectivity, extinction coefficient, refractive index, and real and imaginary parts of dielectric constant were studied. The results were shown that all properties that were studied increases by the ratio of dopping except transmission which decreased at dopping.
