چکیده
The application of green phosphorescent complex Tris[2-phenylpyridinato-C,N]iridium(III) Ir(ppy)3 as a dopant in the hole transporting layer (HTL) of Organic light emitting diode (OLED) structure: HTL/ElL/ETL has been studied. We have found that devices containing from 4 wt.% 6 wt.% Ir(ppy)3 emit pure green light with CIE (x;y) chromaticity coordinates 0.2969; 0.4860 0.3184; 04905 very close to these of the ideal green color 0.3; 0.6, which is recommended at the displays manufacturing.

High efficiency green phosphorescent top-emitting organic light-emitting diode with ultrathin non-doped emissive layer
Ultrathin non-doped emissive layer (EML) has been employed in green phosphorescent top-emitting organic light-emitting diodes (TOLEDs) to take full advantages of the cavity standing wave condition in a microcavity structure. Much higher out-coupling efficiency has been observed compared to conventional doped EML with relatively wide emission zone. A further investigation on dual ultrathin non-d...

Two new hole transporting materials, 2,7-bis(9,9-diphenylacridin-10(9H)-yl)-9,9' spirobi[fluorene] (SP1) and 2,7-di(10H-phenothiazin-10-yl)-9,9'-spirobi[fluorene] (SP2), were designed and synthesized by using the Buchwald-Hartwig coupling reaction with a high yield percentage of over 84%. Both of the materials exhibited high glass transition temperatures of over 150 °C. In order to understand t...
