Dear Sang,

Thank you for your reply to this post. I believe PL quenching and broadening are two different things and both are dependent on measurement temperature. Isn't it?

I understand that the broadening happens due to thermal energy (participation of vibration energy levels) and the quenching happens due to activation of non-radiatve transition at higher temp.

Regards,

Dear Hamit,

Thank you for your references.
