Synthesis of Single Crystalline ZnO Nanobelts by the Solution Route
低温化学法合成单晶氧化锌纳米带

Single-crystalline ZnO nanobelts with non-layered structure were synthesized by the solution route at 100  based on the transformation of the layered precursor (Zn(OH)2 x(CH3COO)x n H2O). The morphology, structure and optical property of the ZnO nanobelts were characterized by transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM), X-ray powder diffraction (XRD), high-resolution transmission electron microscopy (HRTEM) and photoluminescence (PL), respectively. It is indicated that the acetate anion and the weak organic alkali hexamethylenetetramine (HMT) play the critical role in the formation of the layered precursors at the beginning of the process.
