摘要
A new luminescent europium complex [Eu(DBM)3dpq] (DBM = 1, 3-diphenyl-1, 3- propanedionate and dpq=dipyrido[2,3-f][2',3'-h]quinoxaline) has been synthesized and shows intense red emission under UV excitation. With the device structure ITO/TPD/Eu(DBM)3dpq: TPD (1:2)/Gd(DBM)3bath/Mg:Ag, sharp-band red emissions with low turn-on voltage of 3V and high brightness of 304cd m-2 were achieved.
