    • Disclosed are a carbon nano-tube (CNT) light emitting device and a method of manufacturing the same. Specifically, the CNT light emitting device comprises: a CNT thin film formed using a CNT dispersed solution; a n-doping polymer formed on one end of the CNT thin film; a p-doping polymer formed on the other end of the CNT thin film; and a light emitting part between the n-doping polymer and the p-doping polymer. In addition, the method of manufacturing a CNT light emitting device comprises steps of: mixing CNTs with a dispersing agent or dispersing solvent to prepare a CNT dispersed solution; forming a CNT thin film using the CNT dispersed solution; coating a n-doping polymer on one end of the CNT thin film; and coating a p-doping polymer on the other end of the CNT thin film. According to the invention, the n-doping polymer and the p-doping polymer are respectively coated on the CNT having a CNT random network structure to implement a p-n junction, thereby implementing a light emitting device in a simple and low-priced process.
    • 公开了一种碳纳米管(CNT)发光器件及其制造方法。 具体地,CNT发光器件包括:使用CNT分散溶液形成的CNT薄膜; 形成在CNT薄膜一端的n掺杂聚合物; 形成在CNT薄膜的另一端的p掺杂聚合物; 以及n掺杂聚合物和p掺杂聚合物之间的发光部分。 此外,制造CNT发光元件的方法包括以下步骤:将CNT与分散剂或分散溶剂混合以制备CNT分散溶液; 使用CNT分散溶液形成CNT薄膜; 在CNT薄膜的一端涂覆n掺杂聚合物; 并在CNT薄膜的另一端涂覆p掺杂聚合物。 根据本发明,将n掺杂聚合物和p掺杂聚合物分别涂覆在具有CNT随机网络结构的CNT上以实现p-n结,从而以简单且低价格的方法实现发光器件。
