Formation and Properties of 1-D Alumina Nanostructures Prepared via a Template-free Thermal Reaction

A facile template-free thermal reaction was applied to prepare one dimensional (1-D) alumina nanostructures. Through utilizing the anisotropic modules existing in layered structures, the 1-D alumina nanostructures could be controlled to form nanotubes or nanorods with various configuration. The characters were then carefully studied and discussed based on the observation of TEM, XRD and photoluminescence.
