Structural properties of Alq3 nanocrystals prepared by physical vapor deposition and facile solution method

Abstract

Tris(8-hydroxyquinoline) aluminum [Formula: see text] nanostructures are promising materials for nanooptoelectronic devices and molecular spintronics. In this paper, we report [Formula: see text] nanocrystals prepared by both physical vapor deposition (PVD) and facile solution method. The transmission electron microscopy (TEM) and high resolution scanning electron microscope (SEM) measurements show that the [Formula: see text] nanomaterials prepared by PVD technique are [Formula: see text]-[Formula: see text] nanoflowers, while the [Formula: see text] nanostructures prepared by solution method are [Formula: see text]-[Formula: see text] nanorods. Our experiments indicate that the [Formula: see text]-[Formula: see text] nanomaterials prepared by using solution method are more suitable for the fabrication of molecular spintronic devices than that of PVD method.
