Synthesis, characterization and optical properties of CdS nanorods by a simple solution chemistry method

In this paper, we prepared CdS nanorods with controllable size via a facile wet route. Cadmium acetate and sulfur powder were used as precursors and alkylamine and trioctylphosphine (TOP) as solvents in the reactions. Transmission electron microscopy (TEM) studies showed that the length of the nanorods could be controlled by varying ripening time and the amount and types of organic surfactants. Moreover, the result of spectral characterizations demonstrated that the as-prepared nanorods had strong absorption and two photoluminescence emissions in the visible region.
