摘要
The treatment of anodic porous alumina (APA) plates in heated water containing 8-hydroxyquinoline (HQ) produces crystalline tris(8-hydroxyquinoline) aluminum (Alq(3)) microbelts about 5-10 mu m wide and 5-20 mu m long. These microbelts were found to aggregate to formflower-like structures on the surface. X-ray diffraction studies indicated that the Alq(3) microbelts are composed of an alpha-phase having a meridional structure. The Alq(3) microbelts exhibited green photoluminescence with a peak at around 520 nm. Scanning electron microscope images and energy dispersive X-ray spectra showed that this reaction is induced at the APA surface by the reaction between the HQ and amorphous Al2O3 species.
