a Device structures with ionization potential and electron affinity (in eV) for each material (HTL hole-transporting layer, EML emitting layer, ETL electron-transporting layer), and the relevant chemical structures of the materials used in the EMLs. b Normalized EL spectra. c EQE−luminance characteristics and efficiency roll-offs of the OLEDs, in which the black dashed line marks the luminance of 1000 cd m−2, and the green and blue marks represent the device roll-off results at 1000 cd m−2 of the devices based on h-BNCO-1 and BNCZ, respectively.
