We report a novel wet-chemical approach at 180 degrees C for the synthesis of monodispersed ZnO nanorods with high single-crystallinity. The method has successfully brought nanorod diameter from reported 150 nm down to 50 regime in this work. aspect ratio synthesized achieved is exceptionally (in range 30-40). This simple low-cost should promise us future large-scale nanostructures many important applications nanotechnology controlled manner.

Abstract Two methodic concepts, symmetric and asymmetric Ostwald ripening, are elucidated by solution‐route syntheses of oxide sulfide semiconductors. While the original shape a crystallite aggregate forms exterior appearance, preorganization crystallites determines ultimate interior space structure upon ripening. Further investigations on design control solution process will allow construction complex architectures, including nonspherical configurations.
