a Device structure of tandem HF CP-OLEDs. EMLs of blue and green tandem HF CP-OLEDs are 0.5 wt% v-DABNA: 20 wt% (R)-OBN-XT-SXAC: mCBP (20 nm) (device (R)-T-HF1) and 1 wt% BN2: 20 wt% (R)-OBN-XT-SFAC: CBP (20 nm) (device (R)-T-HF2), respectively. b EL spectra, (c) external quantum efficiency–luminance, (d) plots of luminance–voltage–current density, (e, f) CP-EL spectra and plots of gEL versus EL wavelength of the blue (device (R)-T-HF1) and green (device (R)-T-HF2) tandem HF CP-OLEDs using (R)-OBN-XT-SXAC and (R)-OBN-XT-SFAC as sensitizers and v-DABNA and BN2 as emitters.
