| 中文摘要 | lithium acetylacetonate [li(acac)] covered with aluminium was used as an efficient electron injection layer in organic light-emitting devices (oleds) consisting of npb as the hole transport layer and alq(3) as the electron transport and light emitting layer, resulting in lower turn- on voltage and increased current efficiency. the turn- on voltage (the voltage at a luminance of 1 cd m(-2)) was decreased from 5.5 v for the lif/al and 4.4 v for ca/al to 4.0 v for li(acac)/al, and the device current efficiency was enhanced from 4.71 and 5.2 to 7.0 cd a(-1). the performance tolerance to the layer thickness of li(acac) is also better than that of the device with lif. lif can only be used when deposited as an ultra- thin layer because of its highly insulating nature, while the li(acac) can be as thick as 5 nm without significantly affecting the el performance. we suppose that the free lithium released from li(acac) improves the electron injection when li(acac) is covered with an al cathode. |
