一种有机电致磷光白光发光器件（见图），含有掺杂到9 nm厚的宽带隙材料中的绿色、红色和蓝色发光体，显示出获得（26+/-3）1 m W-1的最大前向观看功率效率。高功率效率归因于激子和电荷在发射层内的有效限制、薄的发射层和高效的蓝色电致磷光掺杂剂。
An organic electrophosphorescent white-light-emitting device (see Figure) containing green, red, and blue emitters doped into a 9 nm thick wide-bandgap material is shown to attain a maximum forward viewing power efficiency of (26+/-3) 1m W-1. The high power efficiency is attributed to the efficient confinement of excitons and charge within the emissive layer, a thin emissive layer, and highly efficient blue electrophosphorescent dopant.
