Photons emitted from single-emitters have been discussed as the building blocks of optical science and technology. An essential prerequisite for a successful application of single emitters is to study the photon emission characteristics of them like emission spectrum, polarization state, quantum-yield, coherence length, and etc.. A deeper understanding of those properties can be possibly obtained when a single object is dealt with instead in an ensemble state. For example, a detailed energy level structure and the transition probability between levels can be elucidated from statistical analyses of emitted photons from a single-emitter. In this presentation, in addition to other properties, two interesting phenomena of the single photon emission and the fluorescence emission intermittency (often called blinking) will be discussed in more detail.
