Abstract

Polymethyl methacrylate films are prepared by casting method with various content of InCl3 (2, 4%). X-ray diffraction (XRD) and optical microscope are used to determine the structural properties. Transmittance that determined using UV-Visible spectrophotometer and optical parameters also calculated. Urbach energy values increase with the increasing of InCl3 and energy gap decreased from 3.849 eV of pure PMMA films to 3.230 eV of PMMA-4% InCl3. Dispersion parameters are determined using Wemple-DiDomenico model. Refractive index data at infinite wavelength was found to obey single oscillator model.Keywords: PMMA, Dispersion parameters, Composite, Optical properties.

Abstract

PMMA films with various content of MnCl2 additive (1, 3%) are prepared by casting method. Amorphous films of PMMA-Mn are examined using X-ray diffraction (XRD). UV-Visible spectrophotometer is used to record the transmittance spectra, which decreased with the increasing of MnCl2. Energy gap value decreased from 3.91 eV for PMMA to 3.39 eV for film with 3% additive of MnCl2, while the Urbach energy are increased from 555 meV to 741 meV for the same additives. Dispersion parameters are determined using Wemple and DiDomenico model. The Ed, Eo, and So increased with the increasing of MnCl2 additive, while n (0), λo, and M-1, M-3 are decreased.Keywords: PMMA, Dispersion parameters, Composite, Optical properties.
