It is very important to obtain a deeper understand of the carrier dynamics for indirect‐bandgap multilayer MoS2 and to make further improvements to the luminescence efficiency. Herein, an anomalous luminescence behavior of multilayer MoS2 is reported, and its exciton emission is significantly enhanc...
