Abstract: Semiconductor CdS nanorods were successfully synthesized by the hydrothermal method with monodentate
ligand methylamine as assistant. The obtained CdS nanorods were characterized by using TEM, XRD, Raman, and PL techniques respectively. Effects of the
concentration of methylamine on the morphologies of CdS nanocrystals were investigated. It was found that CdS nanocrystals synthesized displayed
nano-particle, short nanorod, and long nanorod shape when the concentration of methylamine was 1, 5, and 20wt% in the hydrothermal process, respectively.
This indicated that the type of ligand, i.e. bidentate or monodentate ligand, was not the critical factor for the formation of one dimention CdS nanocrystals
in the hydrothermal process. Based on the experimental results, a complex structure-controlling mechanism was proposed.

Key words: cadmium sulfide, methylamine, nanorod, hydrothermal synthesis
