Here, I am talking about silicon nanocrystals.
As we know that the QY =(# of emitted photons / # of absorbed photons) *100 = #%. The number of the absorbed photons can be extracted from the area of the peak absorption and the number of emitted photons can be extracted from the area of the peak emission. So, I just wanna understand the relation between the QY value and the peak-absorption intensity.
Many thanks!
I assume that the QY decreases with increasing the peak-absorption intensity. Please correct me if I am wrong?
Dear Mahmud Sefannaser
I am disagree to using mathematic on atom. To be honest we do not know anything about atom, photon, mass, energy / conservation energy. Thus we must put quantum mechanics perception behind and emphasize to quantum physics and intelligent atom that it can not take any mathematical theorem.

best regards.
Thank you Javad. You are right quantum mechanics can explain a lot about the photophysical properties for these very tiny dots. However, what can the increase of absorption of these dots do with QY? The absorption can be increased because of many reasons and one of these reasons is degradation of the matrix that contain the dots or something happened to the dots themselves.
