Abstract
Gold nanorods exhibit unique and tunable surface plasmon resonance(SPR) derived optical properties in the ultraviolet-visible-near infrared(UV-Vis-NIR) region.The high stability,low biological toxicity,bright color,and versatility of gold nanorods have inspired an explosion of research interest in their properties and applications(which include roles in catalysis,data storage,and biomedicine).This paper presents a brief overview of current research progress on the optical properties of gold nanorods,including surface plasmon resonance,local field enhancement,plasmon coupling,fluorescence,and application outlook.
