Description
本発明は、エレクトロルミネセンス素子に関するものであり、より詳細には高い安定性及び効率のために、燐光性ドープされた混合層構造を利用する、エレクトロルミネセンス素子に関するものである。
電流によって励起させられると光を放出する薄いフィルム物質を使用する、有機発光素子(OLED)は、フラットパネルディスプレイ技術のますます一般的な形体になることが期待されている。これは、OLEDが、携帯電話、個人用デジタル補助装置(PDA)、コンピューターディスプレイ、乗り物の情報ディスプレイ、テレビモニター、及び、光源等の、非常に様々な可能性のある用途を有するためである。それらの色が明るく、視野角が広く、フルモーションビデオに適合性があり、温度範囲が広く、薄く快適な形態という因子をもち、電力要求が低く、並びに、低コストの製造方法の可能性があるので、OLEDは、陰極線管(CRT)及び、増大しつつある年400億ドルの電子ディスプレイ市場に現在優位を占めている液晶ディスプレイ(LCD)の代わりに、将来の代替技術と見られている。それらの発光効率が高いので、電気燐光性OLEDは、或るタイプの用途では、白熱灯、ことによると蛍光灯さえも置き換える可能性があると見られている。
本発明は、燐光性ドープがされた混合層構造を有する発光素子を包含する。これらの発光素子は、基板;陽極(アノード)層;前記陽極層上の正孔注入層;前記正孔注入層上の混合層(この混合層は、正孔輸送物質及び電子輸送物質を含有し、かつ燐光性物質でドープされている);並びに、前記の燐光性ドープがされている混合層上の、陰極(カソード)層、を含む。

「電子輸送物質」は、電荷輸送が主に電子輸送である、電荷担体物質を指す。
「ETL」は、「電子輸送層」を指し、それは唯一のタイプの電荷担体ホスト物質として電子輸送物質を含む層である。
「HTL」は、「正孔注入層」を指し、それは陽極の正孔注入効率を高めるための正孔注入物質を含む。
「正孔輸送物質」は、電荷輸送が主に正孔輸送である、電荷担体物質を指す。
「HTL」は、「正孔輸送層」を指し、それは唯一のタイプの電荷担体ホスト物質として正孔輸送物質を含む層である。
「混合層」は、正孔輸送物質及び電子輸送物質を含む層を指す。
