Hydrothermal synthesis, characterizations and photoluminescence study of single crystalline hexagonal ZnO nanorods with three dimensional flowerlike microstructures.

Highlights: [•] Six faceted single crystalline ZnO nanorods were grown using hydrothermal method. [•] Reaction time and complex reagent plays a vital role to control the morphology. [•] The photoluminescence reveals intense near band edge emission. [•] We report on the growth mechanism of ZnO nanorods. [•] The schematic representation reveals growth habit of ZnO crystal.
