Abstract
A novel anode structure comprising a nanocomposite and metal, has enabled highly efficient and stable superluminescent organic light-emitting diodes (SOLED). For C545T singlet green emitter, SOLED can reach 33 cd/A at 1000 cd/m2, doubled the efficiency as comparing to conventional devices with ITO/CuPc structure. More importantly, the SOLED can still hold 24 cd/A at 50000 cd/m2, indicating a highly efficient hole injection capability at ultra-high brightness. In addition, the simulated electronluminescent spectra with angle dependence, agree with experimental results. It is expected that SOLED might find wide applications, not only in display but in general lighting or ultra-high brightness application, by replacing the problematic ITO anode.
