| 摘 要： | 采用聚乙烯基咔唑(PVK)作为空穴传输层,PF-BT15作为发光层,制备了结构为ITO/PEDOT/PVK(060 nm)/PF-BT15/Cs2CO3/Al的聚合物发光二极管。通过测试器件的电流密度-电压-发光亮度特性,研究了空穴传输层厚度对聚合物发光二级管器件性能的影响,优化了器件功能层的厚度匹配。实验结构表明,聚合物发光二极管的光电性能与空穴传输层的厚度密切相关,当转速约为2 000 r/s,浓度约为1%,膜厚约为40 nm时,其器件光电性能有较大的提高。

| Abstract: | Taking polyvinyl carbazole as hole transport layer（HTL）and PF-BT15 as light-emitting layer,the polymer light-emitting diodes（PLEDs）with the structure of ITO/PEDOT/PVK（0~60 nm）/ PF-BT15/Cs2CO3/Al were fabricated. By testing and analyzing the electric current density-voltage-luminance characteristics,influences of the thickness of HTL on PLED perfor-mance was investigated and the thickness matching of the device′s function layer was optimized. Experimental results show that optical and electrical properties of PLED are closely related to the thickness of HTL,and the photoelectric property of the device is improved more significantly when spin speed is about 2 000 r/s,concentration is about 1% and film thickness is 40 nm. |
