Growth kinetics of nanocrystals in the presence of capping agents is determined by several complex factors, and signatures of either the diffusion or the reaction-controlled regimes are 

Synthesis of ZnO Nanorods. In order to carry out the growth study in the absence of any capping agent, ZnO nanorods were prepared by the reaction of zinc acetate dihydrate (Zn(CH3-C00)2 2H20) and sodium hydroxide in ethanol at 100 °C under solvothermal conditions. The reaction was stopped at different times (I, 2, 3, 6, 12, 18, and 24 h), and the products were analyzed by TEM and SAXS. In a typical synthesis, Zn(CH3- 

ZnO with a polar hexagonal wurzite structure can be described as being due to the hexagonal close packing of the
