摘要：
A novel hybrid encapsulation for organic light-emitting devices was investigated. The hybrid encapsulation consisted of films of polylimide, titanium nitride and stainless-steel foil, and was found to greatly enhance the lifetime of the devices in air. Through optical measurements of the preservation of calcium films encapsulated with a glass cap and in hybrid encapsulation, it was found that the water and oxygen permeation rates of the hybrid encapsulation were of the same order of magnitude as that of the glass cap encapsulation. More importantly, the hybrid encapsulation Is ultra-thin and flexible, making it Suitable for the encapsulation of flexible organic light-emitting devices.
