报道了一种有效的串联有机电致发光器件的连接结构。该连接结构由作为公共电极的薄金属层、在公共电极的一侧上的包含MoO 3的空穴注入层和在另一侧上的包含Cs 2 CO 3的电子注入层组成。这样的连接结构允许有效的相反空穴和电子注入到两个相邻的发射单元中，并且给予串联器件上级电学和光学性能。此外，本连接结构在器件制造期间不涉及溅射或处理活性金属，并且可以纯粹通过热蒸发来制备，从而使器件加工更可行。
An effective connecting structure for tandem organic light-emitting devices is reported. The connecting structure consists of a thin metal layer as the common electrode, a hole-injection layer containing MoO3 on one side of the common electrode, and an electron-injection layer involving Cs2CO3 on the other side. Such a connecting structure permits efficient opposite hole and electron injection into two adjacent emitting units and gives tandem devices superior electrical and optical performances. Furthermore, the present connecting structure involves no sputtering or handling of reactive metals during device fabrication and can be prepared purely by thermal evaporation, thus rendering device processing more feasible.
