Description 771-775
Polyaniline (PANI), polypyrrole (PPy), and polythiophene (PTh) have much more attention in energy applications owing
to their optical and electrical properties. To overcome the problems associated with these polymers, the Up-Conversion
Carbon Quantum Dot (UC-CQD) based materials are employed. That has more desirable features, like hydrophilicity, low
toxicity, and high water solubility. The UC-CQD in the electrochemical field is creating great attention to photoluminescent
behaviors and low specific capacitance. When UC-CQD is combined with the conducting polymers, the optical properties
are enhanced with the help of energy transfer processes. By the advantage of electropolymerization technique, the solubility
problems are tackled, because the monomer has coated on the substrate. Herein, the preparation and characterization of the
UC-CQD doped, PPy, and PTh films have been reported and their optical and electrical properties are investigated. The
band gap of PPy and PPy-CQD is analysed from Tauc plot and calculated to be 2.54 and 1.69 eV respectively. The 50% and
60% mass loss were observed in thermogravimetric analysis for PPy and PPy-CQD respectively. These materials can be
used for organic solar cell applications in near future.
