P-55: Bright and Efficient Stacked White Organic Light-emitting Diodes
نویسندگان
چکیده
High brightness and efficient stacked white organic lightemitting diodes (WOLEDs) have been fabricated based on blue phosphorescent and red fluorescent emissive units consisting of NPB/mCP: FirPic/TPBi and NPB/Alq3: DCJTB/BCP, respectively. White light emission with CIE coordinates of (0.32, 0.38) was obtained. A luminance of 40,000cd/m was obtained using a driving voltage of 26V. The maximum luminous efficiency was about 11.6 cd/A at a current density of 28mA/cm.

Thin-film Encapsulation of Organic Light-Emitting Diodes Using Single and Multilayer Structures of MgF2, YF3 and ZnS
In this research, the lifetime of green organic light emitting diodes (OLEDs) is studied using four passivation layers. To encapsulate the OLEDs, MgF2, YF3, composed of alternating MgF2/ZnS and YF3/ZnS layers were grown by thermal vacuum deposition. Measurements show that the device lifetime is significantly improved by using YF3 and ZnS as passivation layers. However, diodes encapsulated by Mg...
