Abstract

A time-correlated single photon counting system combined with a mode locked $Ar^+$ laser has been utilized to measure the fluorescence decay. A side-on type photomultiplier tube has been used as a photon detector. By restricting the sensitive area and the position of the photocathode, the transit time differencies of photoelectrons in PMT has been reduced. The fluorescence life time of rhodamin 6G in ethylene glycol measured 3.9$\pm$10 ns.
