The nanoflakes synthesized at the lowest temperature (260°C) in this work show an ultra-sharp morphology: 5-10nm in thickness, 1-2μm in length, 20nm in base-width and around 5nm at the tips; successfully demonstrate the promising electron field emission properties of a large-scaled α-Fe2O3 nanostructure film and exhibit the potential applications as future field-emission (FE) electron sources and displays (FEDs). The formation and growth of α-Fe2O3 nanostructures were discussed based on the surface diffusion mechanism.
