Zinc(II) 8-hydroxyquinoline (Znq₂) green luminescent material and its blended thin film in a poly(methyl methacrylate) (PMMA) matrix have been prepared. XRD analysis confirms the formation of the compound and its presence in the PMMA blended thin film. The orbital molecular geometry, quantum chemical calculations and band gap energy of Znq₂ phosphor have been confirmed from the DFT study. The morphology of the phosphor was shown by the SEM images. UV–Vis absorption, photoluminescence and decay analysis of zinc(II) 8-hydroxyquinoline phosphor confirms its suitability as a green emitter for organic light-emitting diodes. Uniform distribution of Znq₂ powder in the PMMA matrix and its roughness was estimated by AFM analysis. Luminescence decay study was utilized to demonstrate its lifetime analysis by the time-correlated single-photon counting (TCSPC) system.
