From: Exciton binding energy and hydrogenic Rydberg series in layered ReS2
(a) Unpolarized PL spectra of 1 L, 2 L, 4 L, 5 L, 6 L and 8 L ReS2 flakes. (b) Polarization-resolved PL and RC spectra of 15 L and 6 L flakes recorded in two linear polarization with the angle between E and b equal to 33° (red line) and 113° (blue line). (c) Energies of different excitonic transitions extracted from PL measurements.
