My nanoparticle has a lower fluorescence life time of 2 ns (usual life time between 3-10 ns). what are the inferences I can get from this?

11 July 2024 1 503 Report

what all details we will get from fluorescence life time data

The fluorescence lifetime is connected to the Einstein coefficients for emission which, in turn, are connected to the frequency and also oscillator strengths (sometimes also reffered to as transition dipole moments):

https://en.wikipedia.org/wiki/Einstein_coefficients#Oscillator_strengths

Assuming your nanoparticles have the same absorption frequency as those you are referring to, the most straightforward interpretation would be that they have a higher oscillator strength.
