Large-area synthesis of single-crystal boehmite nanobelts with high luminescent properties

Ultrasmall 10-nm-wide boehmite single-crystal nanobelts have been prepared by a simple and efficient “molecule tailoring lamella” route with clear advantages over the traditional high-temperature approach for the large-scale production of 1D nanomaterials. Different sized nanobelts can be obtained by only changing the concentration of the tailoring agent. These ultrafine nanobelts should be good candidates for investigating size-induced electrical and optical properties of functional oxides. This novel method has been successfully applied to other ultrasmall hydroxyl nanobelts, such as FeOOH, InOOH.
