Quickly calculate the average lifetime of a photoluminescence decay curve without fitting.

How to use this tool?

It is very simple, all you have to do is choose a photoluminescene decay curve (lifetime) file from your computer by clicking the top left button "Choose file", open the chosen file, the average lifetime result will appear right in the top-right red box, the decay curve will be displyed in the bottom-left box, and all the numerical values involved in the calculations will appear in the bottom-right text area. The average lifetime unit (s, ms, us, ns) will always be the unit of your measurements.

How it works?

The following equation is used in the program to take care of the calculations

where τ represent the average lifetime, t is time and i is the intensity counts.
