| Popis: |
Transparent In-doped (1 at.%) zinc oxide (IZO) thin films are deposited by pulsed DC magnetron sputtering with H 2 mixed Ar atmosphere on glass substrate without any heating process. Even at room temperature, highly c-axis oriented IZO thin films were grown in perpendicular to the substrate. The hydrogenated IZO (IZO:H) film isolated in H 2 atmosphere for 30 min exhibited an average optical transmittance higher than 85% and low electrical resistivity of less than 2.7 x 10 -3 Ω·cm. These values are comparable with those of commercially available ITO. Each of the IZO films was used as an anode contact to fabricate organic light-emitting diodes (OLEDs) and the device performances studied. At the current density of 1 x 10 3 A/m 2 , the OLEDs with IZO:H (H 2 ) anode show excellent efficiency (11 V drive voltage) and a good brightness (8000 cd/m 2 ) of the light emitted from the devices, which are as good as the control device built on a commercial ITO anode. |
