Photoluminescence of Electrospun Poly-Methyl-Methacrylate:Alq₃ Composite Fibres

Tris(8-hydroxyquinoline) aluminium doped poly-methyl-methacrylate (PMMA:Alq₃) composite nanofibres are fabricated by electrospinning. The morphology of fibres is characterized by scanning electron microscopy. The photoluminescence of a series of the nanofibres with various contents of Alq₃ to PMMA is investigated. UV-visible absorption and the PL spectra analysis are employed to analyse the interaction between the polymer and the luminescent molecule.
