| 摘 要： | 合成并用元素分析、红外光谱和核磁表征了共振配合物EuY(DBM)4(Ma)phen2(C1)和Eu2(DBM)4(Ma)phen2(C2).用真空蒸镀组装了发光器件,其结构是:Al0.9:Ag0.1/Alq/Eu-complex/TPD/ITO.在18V电压和55 mA cm-2电流下,器件C1的最大发光亮度是342 cd m-2;在18V电压和57mAcm-2电流下,器件C2的最大发光亮度是267 cd.m-2.在18V电压和55 mA cm-2电流下,器件C1的最大发光亮度是342 cd m-2.C1的发光亮度比C2大,其原因是Y3 的配体吸收的能量通过马来酸根迁移给了Eu3 .

| Abstract: | EuY( DBM)4 (Ma) phen2 ( C1 ) and Eu2 ( DBM)4 (Ma) phen2 ( C2 ) ( DBM: dibenzoylmethane, phen: 1,10-phennanthroline, MA: maleic acid) were synthesized and characterized by EA, IR,and 1 HNMR in this paper. The LED cell was fabricated by conventional vacuum vapor deposition in a vacuum. Their structures are Al0.9: Ag0.1/Alq/Eu-complex/TPD/ITO. The maximum emission intensity of 342 cd m -2 and 267 cd m-2 are observed at 18V and 55 mA cm-2 in the device of C1. The luminescence intensity of the LED with C1 as EML is brighter than that of the LED with C2 as EML. The enhanced Eu3+ luminescence is mostly due to the presence of efficient energy migration from the ligands coordinated Y3+ to Eu3+ through maleic acid bridge. |
