Synthesis and Robust Properties Evaluation of PPY-CuO Nanocomposite for Organic Light Emitting Diodes as Electron Transport Layer Material
The PPY–CuO nanocomposite was synthesized by chemically oxidatively polymerizing pyrrole monomer. The FESEM, TEM and XRD examination revealed the structural properties of the CuO, PPY and PPY–CuO nanocomposites. Increased radiative charge carrier recombination was observed in the PPY–CuO nanocomposite. As resistivity dropped, the recombination in radiative form increased for the PPY–CuO nanocomposite. When compared to the original CuO, the PPY–CuO nanocomposite was shown to have an improved current density of 11.36 A/cm2. It was discovered that the PPY–CuO nanocomposite had higher rates of radiative recombination, improved conductivity and electron mobility, and higher luminescence in the visible spectrum, indicating that it could be used as an electron transport layer (ETL) material in organic light emitting diodes (OLEDs).
期刊介绍：
Protection of Metals and Physical Chemistry of Surfaces is an international peer reviewed journal that publishes articles covering all aspects of the physical chemistry of materials and interfaces in various environments. The journal covers all related problems of modern physical chemistry and materials science, including: physicochemical processes at interfaces; adsorption phenomena; complexing from molecular and supramolecular structures at the interfaces to new substances, materials and coatings; nanoscale and nanostructured materials and coatings, composed and dispersed materials; physicochemical problems of corrosion, degradation and protection; investigation methods for surface and interface systems, processes, structures, materials and coatings. No principe restrictions exist related systems, types of processes, methods of control and study. The journal welcomes conceptual, theoretical, experimental, methodological, instrumental, environmental, and all other possible studies.
