采用气相冷凝法合成了平均粒径为50~500 nm的三(8-羟基喹啉)铝(Alq(3))球形纳米粒子。纳米颗粒的表面非常光滑，就像珍珠一样。X-射线衍射图表明纳米颗粒具有非晶态结构。Alq(3)的化学键即使在410℃蒸发后仍保存在纳米粒子中。纳米粒子的光致发光光谱显示出一个从4500埃到7000埃的展宽峰，最大强度约为5380埃。由于比表面积较大，最大强度随颗粒尺寸的减小而增大。(C)2003年美国物理研究所。
Tris-(8-hydroxyquinoline) aluminum (AlQ(3)) spherical nanoparticles of the average size varying from 50 to 500 nm were synthesized by vapor condensation. The surface of the nanoparticles is quite sleek and smooth like that of pearls. The x-ray diffraction patterns reveal that the nanoparticles have an amorphous structure. The chemical bonding of AlQ(3) is preserved in the nanoparticles even after evaporation at 410 degreesC. The photoluminescence spectra of the nanoparticles show a broadened peak varying from 4500 to 7000 Angstrom, with the maximum intensity at about 5380 Angstrom. The maximum intensity increases as the particle size decreases, owing to the large specific surface area. (C) 2003 American Institute of Physics.
