a Comparison of the linear dichroism between two kinds of hybrid nanostructures. The linear dichroism of the WS2-Ag hybrid is always higher than that of the organics-Ag hybrid at the emission wavelength of the valley excitons (~636 nm). The organics is primarily the fluorescent moieties of PMMA residue. b The linear dichroism induced by the valley coherence (pink curve) and its percentage in the total polarization (green curve). Note that \({\mathrm{LD}}_{{\mathrm{total}}} = {\mathrm{LD}}_{{\mathrm{WS}}_2/{\mathrm{Ag}}}\).
