英文摘要： As the interface of the wearable devices for the next generation, flexible organic light-emitting diodes (FOLEDs) have the important position in this area. The flexible transparent conductive substrate (FTCS) is one of the limited factors for the commercialization of FOLED and is a scientific problem need to solve urgently. It is important to use the polymer-nanomaterials composite transparent conductive substrate to increase the efficiency of FOLED. For the low light extraction efficiency of FTCS and understanding of nanomaterials for light extraction mechanism, we develop the theories of optimization for FTCS through dispersion of nanomaterials and simulation of light extraction process to increase the efficiency of FOLED. In this project, three aspects are mainly focused on:.1..To investigate the mechanism of light extraction effect for silver nanowires-polymer-nanoparticles composite FTCS based on the characteristics of different nanoparticles;.2..To optimize the parameters of FTCS for best light extraction efficiency based on Finite Difference Time Domain simulation;.3..To study the effect of inject, transport and recombination of charge carrier for optimized flexible transparent conductive film and to guide the high efficiency FOLED design theoretically.
