摘要：

The characteristic features of high-efficiency multilayer white-light-emitting polymer light-emitting diodes (PLED), were analyzed. PVK-SO3Li was selected for the hole-injection/transport layer (HIL/HTL) because its HOMO energy level at -5.75 eV is well-aligned with the HOMO energy level of PFO-ETM at -5.80 eV. The reduced turn-on voltage results from the enhancement of the built-in potential in the metal-semiconductor-metal diode by the electron injection/transport layer (EIL/ETL). The results show that high-quality white light make these multi-layer white-light-emitting PLEDs attractive for the development of solid-state light sources.
