Abstract

Abstract: In this study, thin films of PMMA (poly methylmethacrylate) and chalcones are prepared via drop casting method. A newly synthesized Chalcone derivative namely 1‐(3‐Methoxy‐phenyl)‐3‐(4‐napthalen‐yl)‐propenone (C1) are used for doping films with different concentrations. Films prepared are transparent and so they are considered for analysis in photonic applications. Different spectroscopic techniques are used for optical characterization of the samples. From the absorption spectra, optical parameters are determined like band gap energies, refractive index, and extinction coefficient. The way these parameters are affected by doping concentration is studied and plotted graphically. The doping effect is also analyzed on emission spectra. Also, FTIR spectra for doped films is determined and compared with that of the pure compound to notice alterations in the peak values so as to note the change in intensities.
