摘要：

Pure hexagonal aluminum nitride microbelts have been successfully synthesized by directly reacting AlCl3 with NaN3 at low temperature under the condition of non-solvent system. The reaction product (gray-white powder) is characterized by High Resolution Transmission Electron Microscope (HRTEM), the result reveals that the product has a long curling belts morphology with the length of several micrometers. The results of both electron diffraction (ED) and X-ray diffraction (XRD) indicate that the AlN microbelts have a pure hexagonal monocrystalline structure with slight curling. A room temperature photoluminescence spectrum (PL) of the synthesized sample shows an emission peak at 422 nm. The growth mechanism and photoluminescence spectrum of AlN microbelts are discussed.
