文摘
- •
Doping-free, hybrid white OLEDs with fluorescent blue, and phosphorescent green and red emissive layers are reported.
- •
OLEDs with doping-free process show advantages in EL performances over doped devices with similar structures.
- •
Device with ultra-thin green phosphorescent EML in HTL is more efficient in utilization of excitons.
- •
Ultra-thin green phosphorescent EML in HTL makes EL spectrum more stable than that in ETL.
