Boehmite nanorods were synthesized by a solvothermal method using AlCl_3·6H_2O in mixed solvents of water and aniline.The solvothermal time,heating temperature and the concentration of aniline have effects on the morphology of boehmite.γ-alumina nanorods were prepared by a simple thermal transformation of boehmite nanorods.A rational mechanism based on the oriented attachment is proposed for the formation of boehmite nanorods.The products were characterized by X-ray powder diffraction(XRD)and transmission electron microscopy(TEM).Photoluminescence(PL)spectrum of the boehmite nanorods was also investigated.
