Abstract: ZnO nanotroughs were successfully synthesised by a facile hydrothermal route. HMTA/Zn²⁺ molar ratio and reaction temperature played a crucial role in the formation of ZnO nanotroughs. A possible growth mechanism of ZnO nanotroughs was proposed, which may be attributed to the selective etching and dissolution of the preformed ZnO under hydrothermal condition. The ZnO nanotroughs obtained at 200°C exhibited strong ultraviolet emission whereas the visible emission band nearly disappeared and reaction temperature-dependent photoluminescence properties were also observed.
