Abstract

  • Using the new material BPPC, an efficient all-organic NIR OLED having a high quantum efficiency of 5.4% and emitting nearly pure NIR light at λ = 790 nm was demonstrated.
  • The device has a NIR cut-on of λ = 749 nm and more than 90% of the photons emitted are at wavelengths above 750 nm.

Materials & Devices

Device: ITO /HAT-CN(10nm)/ TAPC(60 nm)/ TCTA(10 nm)/ B3PYMPM: EML(0.8wt%BPPC) (40 nm) / TPBi(40 nm)/ LiF/Al(100 nm)




Materials are used by qualified for testing and research only, there are not guaranteed in patent contention by customer use.
