Is PET in your question the same as below?

https://medlineplus.gov/ency/article/003827.htm

A positron emission tomography scan is a type of imaging test. It uses a radioactive substance called a tracer to look for disease in the body.

A positron emission tomography (PET) scan shows how organs and tissues are working .

FRET:

For Inner filter effect , see below:

Himanshu Mishra

Thank you Dr. Xiang. But my question is regarding photo induced electron transfer. And I am looking for an experimental procedure to differentiate among the above said fluorescence quenching mechanisms.

Thanking you.

Himanshu,

Sorry! I only know FRET!

Good luck!
