ABSTRACT

This document describes the measurement of fluorescence lifetime of semiconductor quantum dots (QDs) using time-correlated single-photon counting (TCSPC).

The methods include experimental procedures, data processing, and measurement examples. TCSPC is suitable for measuring fluorescence lifetimes in the picosecond to nanosecond range.

This document applies to stable dispersions of QDs, but not to solid samples.
