Fig. 5: Time-resolved study of WSe2 TBLs luminescence.
From: Phonon-assisted upconversion in twisted two-dimensional semiconductors
a The transient reflected absorption pump-probe detection results of WSe2 ML (top panel) and 5.5° TBL (bottom panel) within 20 ps; solid lines represent fittings based on Eq. (1) (Table S1). b The fluorescence lifetime measurements of ML (blue) and TBLs (warm colors) with various interlayer rotation angles; solid lines represent biexponential fittings (Table S1)
