The novel synthesis and luminescence studies of CuO and Fe2 O3 embedded (8-hydroxyquinoline)zinc nanocomposites

Abstract

The present study investigates the synthesis of novel luminescent polymer nanocomposite through theincorporation of CuO and Fe2 O3 into a C18 H12 N2 O2 Zn host polymer matrix. The observed green electroluminescencebehavior originates mainly from the shift in the HOMO-LUMO energy gap of the polymer matrix caused by the inclusionof oxidized metal/oxygen ions from the incorporated metal oxides into the pyridyl and phenyl groups of the host polymer.The existence of oxidized metal/oxygen ionic states in the polymer matrix is successfully confirmed through X-rayphotoelectron spectroscopic analysis. The FTIR analysis is utilized to verify the presence of pyridyl and phenyl groupsin the host polymer matrix. The successful incorporation of CuO and Fe2 O3 into the host polymer matrix is examinedthrough FESEM and HRTEM analyses. XRD, EDS, and XPS analyses are employed in order to confirm the exactcrystalline phase and material compositions of the samples prepared.
