| 摘 要： | 设计与合成了一种基于Pt配合物的新型磷光材料(ppy)Pt(bcam),用其制备了相应的磷光器件,器件的结构为ITO/NPB(50 nm)/CBP(15 nm)/(ppy)Pt(bcam)(0.3-2.0 nm)/CBP(15 nm)/BCP(10 nm)/Alq3(20 nm)/Mg:Ag(200 nm),并对器件的相关特性进行了研究。(ppy)Pt(bcam)磷光器件的最大发光波长为625 nm,器件的最大发光波长随驱动电压变化很小,显示了该器件磷光特性非常稳定;磷光发光层厚度为0.5 nm在驱动电压为24.25 V时亮度达到8 755 cd/m2,电流密度为499 A/m2时得到最大的电流效率3.33 cd/A。

| Abstract: | A new phosphorescent material based on the platinum complex has been synthesized.The phosphorescent devices have been fabricated by adopting the ultrathin film technology.The device structure is ITO/NPB(50 nm)/CBP(15 nm)/(ppy)Pt(bcam)(0.3-2.0 nm)/CBP(15 nm)/BCP(10 nm)/ Alq(20 nm)/Mg:Ag(200 nm).The relative characteristics of the devices are studied.The peak at 625 nm is the emission spectrum of(ppy)pt(bcam),and the emission spectrum of(ppy)pt(bcam) almost has no change at different driving voltage,it is obv... |
