| Abstract: | Double-heterjunction light-emitting diodes(LEDs) based on organic/polymeric thin layers have been fabricated.The structure of the device is as follows:glass(substrate)/indium-tin-oxide(ITO)/PVK/Alq 3/PBD/Alq 3/Al in which the electrons and holes are respectively injected from the Al negative electrode and ITO positive electrode and transported through PVK and PBD layers,into Alq 3 electroluminescent layer.Green light can be observed at forward bias voltage of 4 V,whereas maximum brightness up to 3 000 cd/m 2 can be achieved at forward bias voltage of 10 V with EL peak wavelength of 523 nm. |
