Abstract
A new time-gated synchronization controller is developed for the detection of near-infrared singlet oxygen (1O2) luminescence around 1270 nm, in which the position and width of the sampling gate can be adjusted according to the time-resolved characteristics of 1O2 luminescence in different environments, respectively. Using this controller, the short-lived and long-lived background luminescence can be efficiently suppressed, which dramatically improves the signal-to-noise ratio for the measurement of time-integrated 1O2 luminescence. This new controller has the potential application for the detection of 1O2 luminescence.
