From: High-brightness all-polymer stretchable LED with charge-trapping dilution

Extended Data Fig. 8

PESA measurements of SY/PU film (a), red polymer/PU film (b), green polymer/PU film (c), blue polymer/PU film (d), PFN-Br/PEIE film (e), TFB/PU film (f), PEDOT:PSS/Triton X film (g) and PEDOT:PSS/PR film (h). UV–vis absorption spectra of SY/PU film (i), red polymer/PU film (j), green polymer/PU film (k), blue polymer/PU film (l), PFN-Br/PEIE film (m) and TFB/PU film (n). Optical bandgap was estimated from the absorption edge of as-cast thin film. HOMO energies were determined by UV PESA. LUMO energies were calculated according to ELUMO = Eg + EHOMO.
