摘要
An organic electrophosphorescent white‐light‐emitting device (see Figure) containing green, red, and blue emitters doped into a 9 nm thick wide‐bandgap material is shown to attain a maximum forward viewing power efficiency of (26±3) lm W –1 . The high power efficiency is attributed to the efficient confinement of excitons and charge within the emissive layer, a thin emissive layer, and highly efficient blue electrophosphorescent dopant.
