- Title:High Performance Red Phosphorescent Organic Light-Emitting Diodes with Blue Common Layer by Solution Process
- Ye Ram Cho and Min Chul Suh (KyungHee Univ., Korea)
Abstract: we used the small molecular mixed host system that has advantage in terms of charge transport property leading charge balance in emission layer. In addition, using the small molecular mixed host system in solution process can quite freely change the composition of host so that optimization for improving device characteristics can be more realistic compared with vacuum evaporation method. In this report, we fabricated the high performance red phosphorescent organic light-emitting diodes with blue common layer by solution process with changing the ratio of two types (PH and NH) of hosts. As a result, we obtained best performance in PH : NH = 7:3 (the current efficiencies at maximum and 1000 nit were 25.9 cd/A and 23.4 cd/A, respectively).
