Edinburgh Instruments offers two types of photon-counting methods for time-resolved photoluminescence: Time-Correlated Single Photon Counting (TCSPC) for luminescence lifetimes between 5 ps and 50 µs, and Multi-Channel Scaling (MCS) for lifetimes between 1 µs and 10 s. In this technical note we present different examples of source and detection method combinations and show how the choice of configuration affects the measurement quality. Focusing on the FS5 and FLS1000 spectrometers, we introduce the new capability of EPL and EPLED pulsed diodes as MCS sources, which helps bridge the gap between TCSPC and MCS.
