Line Plot from Scientific Research

EL spectra of three representative ternary systems: upon adding PC71BM, the EL spectra gradually show the guest binary EL (PM6: ITCC: PC71BM); the dashed arrows on the EL spectra are guides for the eyes to indicate the gradual change of the EL spectra. The insets depict the relative energy levels (exact values in Supplementary Table 7) and the relatively high luminescence quantum yields of the host CT states (indicated by the thicker arrows) and the relatively low luminescence quantum yields of the guest CT states (indicated by the thinner arrows).
