Organic bistable light-emitting devices (OBLEDs) with an aluminum (Al)-nanoparticle-embedded tris(8-hydroxyquinoline)aluminum (Alq3) layer and double emitting layers (EMLs) were fabricated to investigate their color switching behaviors. Scanning electron microscopy images showed that Al nanoparticles were formed on the Alq3 layer. The Al nanoparticles in the Alq3 layer improved the storage margin...
The electrical and the optical properties of organic light-emitting devices (OLEDs) utilizing a 4,7-diphenyl-1,10-phenanthroline (BPhen) and aluminum tris(8-hydroxyquinoline) (Alq 3 ) co-host electron transport layer (ETL) has been investigated to clarify the origin of the luminance efficiency enhancement. The luminance efficiency of the OLEDs was significantly enhanced by utilizing a BPhen:Alq...
