Witryna30 wrz 2010 · Hi There, I have been working on fluorescence decays of the fluorophores whose lifetimes are comparable to the instrument response function (IRF) of my device. The technique I use is based on Time-correlated single photon Counting (TCSPC). I have been fitting the decay curves using multiple exponentials in Origin 8, which fits it on …

WitrynaThe right way to do it is to do Prony estimation and use the result as the initial guess for least squares fitting (or some other more robust fitting routine). Prony estimation does not need an initial guess, but it does need many points to yield a good a estimate. Here is an overview http://www.statsci.org/other/prony.html Witryna12 kwi 2024 · Concerning the decay times, the average decay time was estimated through a non-single exponential decay fit, assuming 3 decays (a fit with 2 exponential decays was considered only for the CDN excited at 450 nm), with a time resolution of about 0.8 ns over the investigated 100 ns time windows (evaluated …
