为了提高红色有机电致发光器件的亮度和效率,引入Alq3∶Mg/WO3作连接层制备了红色迭层有机电致发光器件。通过调节WO3的厚度得到了最佳器件,其效率和亮度达到了普通器件的三倍和四倍。利用铕配合物[Eu(DBM)3bath]和小分子染料器件(DCJTI)单元进行组合制备迭层器件,结构为ITO/TPD/DCJTI∶CBP/BCP/Alq3/Alq3∶Mg/WO3/TPD/Eu(DBM)3bath∶TPD/Eu(DBM)3bath/LiF/Al,器件的最大亮度达8609 cd/m2,最大效率达10.2 cd/A。
In order to improve the brightness and efficiency of the red organic electroluminescent device, a red laminated organic electroluminescent device was prepared by introducing Alq3: Mg / WO3 as a connecting layer. By adjusting the thickness of WO3 get the best device, the efficiency and brightness of three times and four times the average device. The stacked devices were fabricated using a europium complex [Eu (DBM) 3 bath] and a small molecule dye device (DCJTI) cell with a structure of ITO / TPD / DCJTI: CBP / BCP / Alq3 / Alq3: Mg / WO3 / TPD / Eu (DBM) 3bath: TPD / Eu (DBM) 3bath / LiF / Al with a maximum brightness of 8609 cd / m2 and a maximum efficiency of 10.2 cd / A.
