Cs2CO3掺杂石墨烯为电子注入层的有机电致发光器件
摘要：
本发明属于有机电致发光器件领域，具体涉及一种采用Cs2CO3掺杂石墨烯为电子注入层来提高器件效率和亮度的有机电致发光器件，该有机电致发光器件的结构依次包括：ITO阳极、空穴传输层、发光层兼电子传输层、电子注入层、阴极，所述的电子注入层为Cs2CO3掺杂石墨烯，采用有机气相沉积的方法将Cs2CO3和石墨烯同时加热蒸发，然后沉积到ITO玻璃上得到其薄膜，该器件具有操作简单、高效率、制备成本较低的特点。
摘要（英）：

The invention belongs to the field of organic light-emitting devices, and particularly relates to an organic light-emitting device using Cs2CO3 doped graphene as an electron injection layer to improve the efficiency and brightness of the device. The organic light-emitting device sequentially comprises an ITO anode, a hole transport layer, a luminous layer, an electron transport layer, an electron injection layer and a cathode. The electron injection layer is composed of Cs2CO3 doped graphene, and Cs2CO3 and graphene are heated and evaporated at the same time through organic vapor deposition and then deposited on ITO glass to form a film. The device has the characteristics of simple operation, high efficiency and low cost of preparation.
