Abstract
In this paper, we report a facile method to perform microsphere organization of ZnO nanotubes. Study shows ZnO nanotubes with diameters of 80–150nm and lengths of 1.2–2μm were assembled into 3–4.5μm microsphere superstructures, the significance of these assembled ZnO nanotubes is that one-dimensional anisotropic ZnO building blocks are selectively aligned into highly symmetrical three-dimensional isotropic conformations, which may promise us new types of ZnO applications. These microsphere assemblies of ZnO nanotubes have a wide visible yellow emission at 600cm−1. The assembly mechanism was also proposed, the addition of metallic zinc species into linear poly ethylene glycol (PEG) containing ethanol and water mixed solution led to aggregation of PEG polymer coils to Zn(II)/PEG globules with a diameter of ∼500nm, the globule turned into tube-like-structured ZnO–PEG microsphere assemblies (∼2μm) after ultrasonic pretreatment, ZnO nanotubes were formed by the oriented attachment and Ostwald ripening of ZnO growth units onto the tube-like structures during the following hydrothermal process.
