This is one of the most difficult time regimes in which to make accurate emission lifetime measurements, but for Iridium based phosphors used in phosphorescent OLEDs it is very important to be able to accuratly determine their properties. We have developed two methods to make accurate measurements in the microsecond, one based gated iCCD detection, the other using gated photon counting and a novel super continuum laser source from Fanium.
