We have investigated the effect of hole transporting materials in phosphorescent white polymer light-emitting diodes. The doping of a hole transporting material TCTA (4,4′,4″-tris(N-carbazolyl)-triphenylamine) resulted in enhanced luminance and efficiency while the doping of other hole transporting materials degraded the device performance. The effect of hole transporting materials on the performance...
We have showed that the doping of an organic salt into a PVK-based polymer emissive layer could enhance the carrier balance greatly to result in higher luminance and luminous efficiency. It is found out that the salt-doped devices show the similar operating characteristics of frozen-junction light-emitting electrochemical cells (LECs). With the salt doping of 0.6wt.% and an appropriate salt activation...
