Time-resolved fluorimetry via a new cross-correlation method.
A new instrument for the measurement of short fluorescence lifetimes is discussed and characterized. The instrument is basically an implementation of the cross-correlation between the excitation source and the induced fluorescence response. Such an approach, with a mode-locked argon-ion laser as the source, is shown to be capable of measuring lifetimes as short as 80 psec with a precision of 10 psec.
