| Research Abstract |
Photon antibunching behavior in the emission from a single quantum dot(QD), a single QD-organic dye complex, and a single QD-silver nanoparticle complex systems were investigated using single molecule spectroscopy technique. The influence of a size of the QD and a pulse-width of the excitation laser on photon antibunching behavior was revealed for the single QD. After that, photon antibunching of the complex systems by the selective excitation of the QD were investigated.
