摘要：
High-quality Al tris-quinolate (Alq(3)) mixtures with oxasene Nile Blue (NB) layers were grown on glass substrates by thermal evaporation under vacuum. The photo-luminescence spectra show three distinctive peaks and their relative intensities change with mixture relative concentrations. The major emission peak at 4100 +/- 70 Angstrom has been identified. The I-V characteristics show a Schottky diode behavior for thin film double layers of NB-(Alq(3)-NB) mixture. Planer Blue Laser emission tool; place parallel to the substrate surface and perpendicular to the electric field direction starting at V = 0.28 +/- 0.05 V. Threshold current of 0.088 +/- 0.012 mA and optical power densities up to 0.5 mW/cm(2) were determined. (C) 1998 Published by Elsevier Science B.V.
