Main Results:

A novel emission regime at intermediate brightness levels was identified, characterized by delayed luminescence.
This delayed emission is attributed to a reversible charge trapping process.
Stochastic switching between active and inactive reversible trapping states was observed within individual nanoplatelets.
At higher excitation powers, non-radiative quenching pathways dominate over reversible trapping.

Conclusions:

Reversible charge trapping plays a critical role in the emission dynamics of CdSe/CdS nanoplatelets.
Understanding these trapping dynamics is crucial for optimizing their optoelectronic applications.
The observed emission regimes provide insights into the fundamental photophysics of nanomaterials.
