Description

これに対し、M. A. Baldoらは室温で励起三重項状態から燐光発光するイリジウム錯体等を用いることにより外部量子効率7.5％（外部取り出し効率を２０％と仮定すると内部量子効率は37.5％に相当する）を得、従来上限値とされてきた外部量子効率５％という値を上回ることが可能なことを示した。さらに、ホスト材料や素子構成を工夫することにより２０％近い高効率も達成されており（非特許文献２：Appl. Phys. Lett., 90巻, 5048頁, 2001年）、超高効率化の方法として注目されている。これは、具体的には、４，４'−Ｎ，Ｎ'−ジカルバゾールビフェニル（ＣＢＰ）等をホスト材料に用いるものである（特許文献１：国際公開第01/41512号パンフレット）。   On the other hand, MA Baldo et al. Use an iridium complex that emits phosphorescence from an excited triplet state at room temperature to achieve an external quantum efficiency of 7.5% (assuming an external extraction efficiency of 20%, the internal quantum efficiency is equivalent to 37.5%) It was shown that it was possible to exceed the value of 5% of the external quantum efficiency that has been conventionally set as the upper limit. Furthermore, high efficiency of nearly 20% has been achieved by devising the host material and device configuration (Non-patent Document 2: Appl. Phys. Lett., 90, 5048, 2001). It is attracting attention as a method. Specifically, 4,4′-N, N′-dicarbazole biphenyl (CBP) or the like is used as a host material (Patent Document 1: International Publication No. 01/41512 pamphlet).
