Research Abstract

To precisely elucidate the properties of electron-cation pair produced by the photoionization in the condensed phase, the detection system with a single molecular level was designed. In relation to this aim, the role of the photo-ionized state in the fluorescence blinking process was elucidated by using a single molecule fluorescence detection system of the guest dye molecule in the micro-droplet of the nonpolar solution.
