In this paper, CdSe nanorods were prepared via solvothermal synthesis, the effect of surface ligands on the morphology of nanorods was investigated under the premise by tuning the percentage of surface ligands in the precursors. Experimental results show that the absorption and emission spectrum of CdSe nanorod with different aspect ratio varying from 4:1 to 2:1 have a red-shift, and the aspect ratio gradually decreases as the percentage of tetradecylphosphoric acid (TDPA) in the precursor increases. In addition, the CdSe optical stability improves as the percentage of TDPA increases. It is also shown that the crystal surface, which is not covered by TDPA, has an increased surface energy, which results in rapid growth of the crystal face and the formation of a rod-like structure. As a result, the effects of anisotropic absorption and emission, along the long axis properties can find many applications in the fields of optics, optical materials.
