Fig. 4: Power-dependent PL properties of WSe2/WSe2 twisted homobilayer.
From: Evidence for moiré intralayer excitons in twisted WSe2/WSe2 homobilayer superlattices

a The normalized PL spectra of different excitation powers range from 0.01 to 3 mW, the excitation photon energy is 2.33 eV, and the energy resolution is 3 meV. b The normalized PL spectrum of T-HB as a function of power (0.01 mW~3 mW), and the data come from Fig. 4a. c The geometric shapes of different colors correspond to the positions of different energy peaks, from Fig. 4a. The PL intensity of different peak positions under different excitation powers
