Phosphorescence Lifetime
Phosphorescence lifetimes, occurring as emissive decays from the triplet-state, can also be approximated as those decays occurring in the time region from tens of nanoseconds to seconds.
Phosphorescence lifetime measurements are carried out using a technique called Multi-Channel Scaling (MCS) and this is used for the acquisition of sample decays.

Description
Photons are counted in a time window which sweeps across the full time range following each excitation pulse, creating a histogram of counts versus time. The data quality of the resulting histogram is improved by adding the data of repeated sweeps.
The sample is excited, and data are collected repetitively with a low to medium repetition rate source, such as the standard microsecond flashlamp (μF2), or lasers operating in the kHz regime.
