12‐4: Blue OLEDs Fabricated by Close‐Space Sublimation

A close‐space sublimation process (CSS) was used for the deposition of blue emitting layers (EMLs) with a host‐dopant composition. Blue EMLs with a uniform dopant distribution were obtained using a pair of host and dopant with matching evaporation characteristics. Blue OLED devices fabricated via CS...

Zusammenfassung:A close‐space sublimation process (CSS) was used for the deposition of blue emitting layers (EMLs) with a host‐dopant composition. Blue EMLs with a uniform dopant distribution were obtained using a pair of host and dopant with matching evaporation characteristics. Blue OLED devices fabricated via CSS with improved performance were demonstrated.
