We have option to choose maximum peak counts upto 10000. How can one select peak counts?
I choose time range upto 90% decay. Suppose if the decay complete 90% at 1000 ns, I choose 2000 ns pulse period. Is it the right way for data collection?
As you are working on perovskites, a good sync rate is to start with 300 kHz (till 2 MHz). If you use a higher repetition rate, you generate new charges in the film while the previous ones are not decayed yet. Ideally, very good perovskite films (with almost negligible defects) live up to 1 us (at low laser fluence (order of nj/cm^2). A better approach is to use a similar integration time, let's say, 300 s, in order to have same background noise for different films. You carriers lifetime will anyway be less than few hundreds of nanoseconds.
@Azhar Fakharuddin and Peter Kapusta. Thank you so much. Peter Kapusta enhanced my confidence to fight with reviewer's comments many times by answering my questions.
Dear all, I have TRPL measurements of films with different decal time range. Lets say 50ns, 200 ns, and 500 ns for different films. Can we correlate exciton lifetime and decay time for that results?. OR should I record it with same decay time range?
