中文摘要： 本项目提出一种由石墨烯作透明电极，将有机分子-金属氧化物复合薄膜(有机-无机复合薄膜)用作红外探测材料，与有机发光器件(OLED)单片集成红外-可见光转换器，它可将红外光在复合薄膜中产生的光电流直接注入到OLED中发出可见光，从而实现红外光到可见光的信号转换。本项目拟从这种复合薄膜的制备及物理性质入手，研究在复合薄膜中产生红外吸收的物理机制(CTC机制)及其红外吸收特性；同时研究红外探测材料与石墨烯电极和OLED的界面结构，揭示红外光电流的产生、传输及红外光到可见光的转换机制；通过材料的选择和器件结构的优化，实现红外-可见光转换器的高效率高稳定性，以及大气窗口中特殊波段的近红外光(约1.5μm)到可见光(约0.5μm)的光-光转换。本项目将探索出制备通讯窗口用的红外探测材料的新方法,并开拓红外探测材料与有机器件集成的新领域，为开发新型红外探测与成像系统提供科学依据和技术支持。

英文摘要： The project proposes a transparent electrode made of graphene, organic molecule - metal oxide composite thin film materials used for infrared detection, and organic light-emitting diode (OLED) monolithic integrated infrared light - visible light converter, which converts infrared light into a photocurrent which then drives OLED to produce visible light. The project research scope includes studying physical properties of organic - inorganic composite thin-films, physical mechanism (CTC mechanism) causing IR absorption, graphene electrodes and its interface with infrared detection materials, interfacial physical properties between infrared detection materials and OLED. Through a combined effort in choice of materials and optimization of the device structure, the goal is to demonstrate a new type of IR - visible converter, which is capable of converting near infrared band (about 1.5 μm) to visible light (about 0.5 μm). This research project will develop a new approach to develop infrared absorption material for the communication window using organic-inorganic composites and a new method to integrate OLED on IR materials for converting invisible electromagnetic wave into visible light.
