| Abstract: | The principle of optical detection for three-levels single molecule in room temperature were introduced.By use of Hanbury-Brown-Twiss method,the photon statistics P(n,n=0,1,2) and the Mandel parameter were analyzed by recording of every photo-electrical event from the single photon source.In the work,novel and fast approaches for identifying single molecules and the determination of signal to background ratio were presented based on single event photon statistics. |

| Keywords: | single molecule single event mandel parameter photon statistics |
