Description
Summary:The controlled growth of zinc oxide nanorods in aqueous�solution is reported. Zinc oxide (ZnO) micro- and nano-rods were successfully prepared on gold-seeded Si substrates in aqueous so�lution containing 1:1 ratio of varying concentrations of zinc ni�trate hexahydrate (Zn(NO3)2.6H2O) and hexamethylenetetramine (HMTA) (C6H12N4). The ZnO rods were characterized by scan�ning electron microscopy, X-ray diffraction and photolumines�cence (PL) spectroscopy. A unique evolution of size and growth orientation is directly affected by the change in concentration of Zn2+ solution. The mechanism of growth governed by HMTA and chemical equations are suggested.
