a Schematic device structure and energy-band diagram of the OLED using m-MTDATA/T2T bilayer. b EL spectra of m-MTDATA/T2T bilayer OLED in various applied biases. Inset: Magnification of Fig. 5b in the range of 2.6–3.2 eV for XFm-MT. c EL peak positions for the XPm-MT/T2T bilayer OLED (red markers) as a function of applied bias. Inset: EL peak positions (blue markers) for the XPm-MT:T2T CDL OLED. d EL intensities of XPm-MT/T2T in the bilayer (red markers) and CDL (blue markers) OLEDs as a function of applied bias.
