    Abstract Copper-doped ZnO (CZO) nanoflower and nanoellipsoids were synthesized by hydrothermal method. Field emission electron microscopy and transmission electron microscopy revealed that the flower-like morphology of undoped ZnO transformed into nanoellipsoids upon incorporation of copper (Cu) in ZnO. Raman spectra of copper- doped ZnO showed E2L peak shift compared with undoped ZnO nanoflower which indicated enhanced oxygen or zinc vacancy in copper-doped ZnO. Low-temperature ammonia gas sensing properties based on copper-doped ZnO were systematically studied. Cu-doped ZnO (6wt%) showed enhanced selectivity compared with other copper doping (wt%). Furthermore, the Cu-doped ZnO showed an excellent response and recovery time at a low concentration of ammonia (10ppm). Cu-doped ZnO showed better long-term stability and reproducibility towards ammonia gas. Highlights ZnO nanorods, Cu-doped ZnO nanoflower and nanoellipsoids were successfully synthesized. CZO nanoellipsoids showed enhanced oxygen vacancies compared to undoped ZnO. Cu-doped ZnO (6%) showed maximum response of 32.32 for 100ppm at 150°C. Cu-doped ZnO showed long-term stability and repeatability. Fast response and recovery time was obtained. Graphical abstract [DISPLAY OMISSION]
