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+。
The complex complexes EuY (DBM) 4 (Ma) phen2 (C1) and Eu2 (DBM) 4 (Ma) phen2 (C2) were characterized and characterized by elemental analysis, IR and NMR. The light-emitting device was assembled by vacuum evaporation and its structure was: Al0.9: Ag0.1 / Alq / Eu-complex / TPD / ITO. The maximum luminance of device C1 is 342 cd m-2 at 18V and 55 mA cm-2. The maximum luminance of device C2 is 267 cd at 18V and 57mA cm-2. m-2. At 18V and 55 mA cm-2, the maximum brightness of device C1 is 342 cd m-2. The luminescence intensity of C1 is larger than that of C2 because the energy absorbed by the ligand of Y3 + migrates to Eu3 + through the maleate.
