| 英文摘要 | Two kinds of OLED configurations (ITO/TPD/Alq3/LiF/Al and ITO/α-NPD/Alq3/LiF/Al) have been prepared successfully by the vacuum deposition system to fabricate the organic layers and cathode of organic light-emitting diodes (OLEDs) upon the indium-tin-oxide (ITO) coated glass substrate under a base pressure lower than 5.5 × 10-6 torr. The 4,4'-bis[N -(1-napthyl)-N -phenyl-amino]-biphenyl(α-NPD) and N,N'- Diphenyl-N,N'-di(m-tolyl)benzidine (TPD)are used as hole transport layer (HTL).The Tris(8-hydroxyquinoline)aluminum (Alq3) is used as light-emitting layer (EML) and electron transport layer (ETL). The elecon injection layer of 0.5 nm thick LiF and cathode of 300 nm thick AI were evaporated on the top of organic layer. Compared to自e device with TPD/Alq3 as organic layer, the device with the organic layer of a-NPD/Alq3 is found to have better performance. With regards to OLEDs with a-NPD/Alq3 as organic layer with different thickness of hole and electron transport layers, the a-NPD (40nm)/ Alq3(30nm) was found to achieve the best efficiency. Its luminance can reach 23214 cd/m2 at 10.2 V quickly while the other device with the thickness of 30 nm /40 nm has 15754 cd/m2 luminance at 9.6 V. |
