Abstract

Water diffusion through a single-layer barrier is measured with Secondary Ion Mass Spectrometry, electrical capacitance, and mechanical film stress. The time taken for one monolayer of water molecules permeate into the OLED is defined as the lifetime. Extrapolated to T = 38°C and 90% relative humidity, a 3μm thick barrier is predicted to seal for 13 years.
