  • Abstract In recent years, the Surface Plasmon Polariton effect has played an important role for entering the Nano-world. When the metallic materials reach the nanometer level, many special characteristics show up. As the progress of advanced technology development, the equipments which can be operated in nano grade level are more stabilized. Many special surface Plasmonic properties have been discovered through the measurements. This research is to focus on using the Surface Plasmon coupling to excite colloidal quantum dots and observing the emissive behavior of quantum dots. The experiments of changing the distance between the quantum dots and the metal film were performed. The blinking effect disappeared when the quantum dots are very close to the metal film. It showed that some other mechanism is competing with Auger recombination in the quantum dots. The lifetime modification and emission intensity were measured when one quantum dot was placed near a silver cube. The coupling between the surface Plasmon polariton and the quantum dot was discussed.
