How can I find the HR factor like we calculate the Debye waller factor as - log(IZpl/Itotal), from the intensity profile of the PL spectra.

  • $\begingroup$ Is the PL spectrum obtained from experiment or computation? $\endgroup$

  • $\begingroup$ @wzkchem5 in the absence of more information, I'd write an answer based on it literally being a PL spectrum (from a PL experiment). I guess the OP needs to fit a spectral density model containing the HR factor, to best reproduce the PL spectrum, so the HR factor would be obtained from fitting. You probably know better than me though! $\endgroup$ Commented Jul 31, 2023 at 14:22
  • $\begingroup$ Pl spectra is obtained from an experiment and also HR factor is no a fitting parameter $\endgroup$
