Longevity of organic light-emitting devices by means of polyacrylate passivation layers formed by using spin coating method

摘要

We fabricate organic light-emitting devices with polyacrylate passivation layers formed by using spin coating method and compare the rate of degradation to an organic light-emitting device without the passivation layer. The fabrication process of passivation layer did not influence the electrical and the emissive properties of the device. Polyacrylate passivation layers enhanced the longevity of the device than that of the non-encapsulated device, and its behavior was dependent on the polyacrylate film thickness.
