Time-Resolved Fluorimetry Via a New Cross-Correlation Method,

Abstract

A new instrument for the measurement fo 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 80ps with a precision of 10ps. The instrument is simpler and less costly than others of similar capability.
