Inner filter effect (IFE) was previously considered as an error in fluorescence measurement.
In recent years, it has been developed as an important non-irradiation energy conversion …

Among various photophysical processes for fluorescence modulation, inner filter effect (IFE)
is well-known for its simplicity and no requirement of the distances between the fluorophores …

As an essential trace element, selenium participates in numerous important life processes
and plays a significant role for human beings. Owning to its unique physical, chemical and …

In this work, we reported a green route for the fabrication of fluorescent carbon dots (CDs).
