2D- semiconductors with strong light-matter interaction are attractive materials for integrated and tunable optical devices. Here, we demonstrate room-temperature wavelength multiplexing of the two-primary bright excitonic channels (Ab-, Bb-) in...

We measure the second-order coherence function g(2) for X-ray-driven light emission (scintillation), observing that it is bunched (g(2) > 1), and can achieve extreme bunching values (g(2)~97) in perovskite nano-crystals.
