(Color online) Schematic structure and corresponding circuit of the optocoupler.
(a) Current-luminance-voltage characteristic of PLED. Inset: luminance vs current. (b) characteristic of the photodiode under AM1.5G illumination. Inset: short-circuit current density dependence on the incident light intensity. (c) EL spectrum of PLED and EQE for the photodiode.
(a) Current of the photodiode vs voltage of the PLED with photodiode under no bias condition. (b) Current transfer characteristics: current of the photodiode vs current of the PLED . Inset: current transfer ratio vs .
