制造了量子效率超过 100% 的多光子发射 (MPE) 有机电致发光 (OEL) 器件的新颖结构。该器件的原理是多个传统的OEL结构（发射单元）堆叠并被电荷生成层（CGL）划分，电荷生成层在施加电压时充当电子空穴对的注入器。三重堆叠 MPE 成功实现了荧光绿色染料香豆素 C545T 的发射达到 48 cd/A。
Novel structure of Multiphoton Emission (MPE) organic EL (OEL) device capable of exceeding 100% quantum efficiency was fabricated. The principle of the device is that a plurality of conventional OEL structure (emissive unit) are stacked and divided by Charge Generation Layer (CGL) that works as an injector of electron‐hole pair upon voltage application. Tripled stacked MPE successfully achieved 48 cd/A for the emission from fluorescent green dye coumarin C545T.
