Tris(8-hydroxyquinoline) aluminium doped poly-methyl-methactylate (PMMA:AIq3) composite nanofibres are fabricated by electrospinning.The morphology of fibres is characterized by scanning electron microscopy.The photoluminescenee 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.
