摘要：
We have developed high-efficiency tandem white organic light-emitting devices (OLEDs) featuring emission layers comprising a blue light-emitting host material [1,3,5-tris(1-pyrenyl)benzene (TPB3)] obtained by high deposition rate, doped with red light-emitting guest material [4-(dicyano -methylene)-2-tert-butyl-6-(1,1,7,7 tetramethyljulolidyl-9-enyl)-4H-pyran (DCJTB). The device exhibited a maximum luminance of 72100 cd/m(2), a maximum power efficiency of 3.44 lm/W at 8V, and a maximum external quantum efficiency of 4.72% at 20V.
