GETTER COMPOSITION COMPRISING ALKALI METAL DOPED MAGNESIUM OXIDE PARTICLE

摘要

The present invention relates to a getter composition comprising magnesium oxide particles doped with alkali metal, a getter layer comprising the same, and an organic electronic device comprising the same. The getter composition comprising magnesium oxide particles doped with alkali metal maintains transparency of conventionally used magnesium oxide particles, and has remarkably improved moisture absorption. Thus, a device sensitive to moisture can be effectively protected by using a getter layer comprising the getter composition.
