N2 - We found that the spin-coated films of NPB, and blends of NPB and DPVBi, though having lower densities, were more uniform than their vacuum-deposited counterparts. Using the spin-coated films of NPB:DPVBi as mixed host, doped with blue dye (4,4′-bis[2-(4-(N,N-diphenylamino)phenyl)vinyl]biphenyl) and yellow dye (5,6,11,12-tetraphenylnaphacene), new white organic light-emitting devices (WOLEDs) were demonstrated. The luminance, efficiency and stability of these solution-processed devices are better than or equivalent to the vacuum-deposited one, which was expected as an alternative route to the fabrication of small-molecular WOLEDs, avoiding the complexities of the co-evaporation of multiple dopants and host materials in the vacuum deposition.
