Highly efficient single-layer dendrimer light-emitting diodes with balanced charge transport
TD Anthopoulos, JPJ Markham, EB Namdas… - Applied physics …, 2003 - pubs.aip.org
High-efficiency single-layer-solution-processed green light-emitting diodes based on a
phosphorescent dendrimer are demonstrated. A peak external quantum efficiency of
10.4%(35 cd/A) was measured for a first generation fac-tris (2-phenylpyridine) iridium cored
dendrimer when blended with 4, 4′-bis (N-carbazolyl) biphenyl and electron transporting 1,
3, 5-tris (2-N-phenylbenzimidazolyl) benzene at 8.1 V. A maximum power efficiency of 12.8
lm/W was measured also at 8.1 V and 550 cd/m2. These results indicate that, by simple …
