Figure 3: Performances of iPLEDs with 2-ME+EA and differently structured ZnO layers.
From: Highly efficient inverted polymer light-emitting diodes using surface modifications of ZnO layer
(a) Current density versus voltage (J–V) characteristics, (b) luminance versus applied voltage (L–V, cd m−2), (c) luminous efficiency (lumin. eff.) versus current density (LE–J, cd A−1), (d) power efficiency versus current density (PE–J, lm W−1), (e) EQE versus current density (EQE–J, %) and (f) normalized electroluminescence (EL) spectra of the iPLEDs. The insets of c–e show LE–J, PE–J and EQE–J on a linear-linear scale.
