i have a doubt for quantum yield u wrote number of photons emitted/number of photons absorbed then it should be radiative rate divide by total rate right..?, i am not sure on this, but can u please explain it.
Does the electronics of TCSPC actually measure a single photon? Enlighten me please. I'm curious about this for a long time. I saw that "single photon" may be defined for a group of pulses. In the last your paper, have you compared the use of "% normalized pre-exponential A1 and A2" vs. "F1 and F2"? where Fi = 100*[αiτi/Sum(αiτi)] PS. Thanks for sharing the presentation
You can never be 100% sure, but in practice we restrict the number of photons going to the detector with either an aperture or a neutral density filter, so that way if a photon comes into the sample, statistically it should likely come from a single photon But the issue of multiple photons coming in and causing pulse pile-up is always something we want to avoid
Very informative! It's a fantastic talk! Thank you!
Great presentation. Very informative and well thought out.

Good catch - there was a typo in the equation. Thank you for pointing that out.
We've added a note to the video and a comment in the description.
Great talk. Much obliged.
Thanks it was really helpful.
I don't understand how to calculate the life time..I understand the process about the fitting...how can we get the life time value?

If single-photons are hard to detect (9:09), how can you be sure you send in a single-photon (9:33)?

@@JeffreyDuBose-kb2rz I'm not convinced, but thanks for trying anyway.
Sir, why is there a peak in your Prompt. Any explanation for this?
THANK YOU SO MUCH !!!!
Is the QY correct? I think it is Kr/(Kr+Knr), isn't it?
A VERY BIG THANKS!
Very nice and handful. Thanks a lot
Thank you.
Thank you
It is really helpful
You often say "again"
Thank you
