Abstract

Abstract : A new method to investigate the influence of vacuum chamber impurities on OLED lifetime is demonstrated. By combining deposition from a novel‐design crucible with in‐situ exposure to impurity sources, and by controlling the amount of water impinging, we show that the influence of water and impurities can be separately examined.
