The unit of pl peak intensity

Post by pangrt » Tue Jul 16, 2024 10:30 am

Dear all,
I am trying to repeat the ex-ph part. I am not clear about the meaning of the intensity of the PL peak calculated in the tutorial. For example, the strongest peak of hBN is about 1.6e-6.
What is the unit of this value? How to compare this intensity with the experiment? Is it just a relative comparison?
If the strongest PL peak intensity of another system is 1.6e-3 at the same temperature, does it mean that the luminescence peak of this system is stronger than that of hBN?

Thanks!

These are arbitrary units, you can just compare the relative intensity of the peak or the comparison with the direct one

Dear Claudio
Thanks for your reply! So, relative strength means that comparisons between different systems are meaningless?
