- Abstract
- Organic thin film transitors(OTFT) are of interest for use in broad area electronic applications. And recently organic electroluminescent devices(OELD) have been intensively investigated for using in full-color flat-panel display. We have fabricated inverted-staggered structure OTFTs at lower temperature using the fused-ring polycyclic aromatic hydrocarbon pentacene as the active electronic material and photoacryl as the organic gate insulator. The field effect mobility is 0.039 ~ 0.17 cm2/Vs, on-off current ratio is 106, and threshold voltage is -7 V. And here we report the study of driving green emitting, Ir(ppy)3, phosphorescent OELD with all organic thin film transistor and investigated its electrical characteristics. The OELD with a structure of ITO/TPD/8% Ir(ppy)3 doped in BCP/BCP/Alq3/Li:Al/Al and OTFT with a structure of inverted-staggered Al(gate electrode)/photoacryl(gate insulator)/pentacene(p-type organic semiconductor)/ Au(source-drain electrode) were fabricated on the ITO patterend glass substrate. The electrical characteristics are turn-on voltage of -10 V, and maximum luminance of about 90 cd/m2. Device characteristics were quite different with that of only OELD.
