Metal semiconductor heterostructure nanocrystals exhibit unique optical properties that make them desirable in applications ranging from photovoltaic cells to molecular imaging studies. This study explores the growth of gold on cadmium sulfide (CdS) and cadmium selenide (CdSe) nanorods. Gold deposition was successfully achieved on both CdS and CdSe nanorods. Furthermore, the amount and position of gold deposited on the CdS nanorods were tuned by varying reaction time and precursor concentration. Future work will focus on optimizing gold deposition parameters on both CdS and CdSe nanorods, and exploring synthesis of and gold deposition on other materials systems.
