a Luminance decays (L/L0) and operating voltage (V − V0) characteristics of 4CzIPN-, ACRXTN-, and 2CzPN-based OLEDs with a constant current density of 3.0 mA cm−2. L and V are the luminance and driving voltage, respectively. L0 and V0 are the initial luminance and driving voltage of degradation test, respectively. b Magneto-electroluminescence (MELJ) profiles of pristine and degraded 4CzIPN-based OLEDs. c Relationship between luminance decay and the amplitudes of low-field and high-field effects in MELJ. d Relationship between luminance decay and the characteristic fields of low-field and high-field effects in MELJ. e Relationship between operating time and the amplitudes of low-field and high-field effects in MELJ. f Relationship between operating time and the characteristic fields of low-field and high-field effects in MELJ.
