摘要：

In this paper, nano-porous AlN micro-rods were prepared and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Brunauer-Emett-Teller (BET) method of nitrogen adsorption at low temperature, UV-via absorption spectrometry and Raman spectrometry. The SEM images and TEM images showed that the AlN samples were micro-size rods with pores in their surfaces evenly. The length of the rod was in the range of a few microns to tens of micron, the diameter of the rods was about one micron, the diameter of the pore was about hundreds of nanometer and the wall thickness of the pore about tens of nanometer. The BET surface area of the sample was 41.424 m2/g. The optical spectra showed that the optical properties of the AlN samples almost agreed with that of AlN bulk or film.
