Abstract
SummaryThis research article was intended to examine the optical properties of as‐synthesized conducting polythiophene (PTh). Thiophene, the monomer of PTh, has been polymerized through chemically oxidative polymerization method in the presence of an oxidant anhydrous ferric chloride (FeCl3). The surface morphology of prepared sample was analyzed through FE‐SEM, which shows irregular structure and spongy amorphous morphology. The UV–vis spectroscopy was performed to study optical parameters. This polymeric material exhibited absorption around 200–250 nm. The optical band gap energy values of prepared samples ranges over 4.033–4.688 eV. The estimated optical band gap energy has accepted value for photovoltaic activities and has potential for application in solar cells and optical devices.
