(a) PL spectra of WS2/hBN measured with excitation power ranging from 0.37 to 6.6 μJ/cm2 at 80 K. (b,c) Plots of PL intensities of trion, P1 and P2 verses that of exciton. Green, blue and red filled squares correspond to PL intensities of P1, trion and P2, respectively. Solid lines corresponds to fitted lines based on the relation of I ∞ I ex α.
