The PPY-CuOnanocomposites was synthesized by chemically oxidatively polymerizing pyrrole monomer. The FESEM, TEM and XRD examination revealed the structural properties of the CuO, PPY and PPY-CuOnanocomposites. 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&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).
