| 摘 要： | 使用柠檬酸钾(C6H5K3O7)作为电子注入材料,制备了多层有机电致发光器件。当柠檬酸钾阴极修饰层厚度为0.5 nm时,得到3.6 cd/A 的发光效率,高于0.5 nm LiF作阴极修饰层时的发光效率(2.5 cd/A) 。器件的开启电压相比0.5 nm LiF作阴极修饰的器件降低了0.5 V。实验结果表明,柠檬酸钾(C6H5K3O7)是一种良好的电子注入材料。

| Abstract: | The multilayer organic light-emitting diodes(OLEDs) using potassium citrate(C 6 H 5 K 3 O 7) as the electron-injection material have been fabricated.The electroluminescence(EL) efficiency of 3.6 cd / A was obtained by inserting 0.5-nm-thick C 6 H 5 K 3 O 7 as electron injecting layer,which is higher than that of 2.5 cd / A in reference device with 0.5-nm-thick LiF.The turn-on voltage was decreased 0.5 V compared with the reference device with 0.5-nm-thick LiF.The results demonstrated that C 6 H 5 K 3 O 7 is a promising electron injection material. |
