Figure 2

Sketch of the low temperature (kBT < ΔSO) photoluminescence spectrum of WX2 including the bright exciton, dark and bright trions (green) and dark and bright biexcitons (red). The excited bright trions and excitons are denoted by T* and B*. The dark exciton (Xd) energy is marked as a reference point .
