有机光电材料光物理特性在线评价系统研制

Organic optoelectronic materials have showing a wide application prospect in the fields of energy, environment, information and biology because of their unique advantages. However, it is still not clear for us to understand some basic photophysical processes (i.e. energy transfer, charge transfer, charge separation and recombination, etc.), which has affected the performance of materials and devices. This is very incompatible with the rapidly growing demand of the organic optoelectronic materials and devices, and it has been one of the core problems that constraints the further applications of organic optoelectronic materials and devices. The lack of the necessary systems and means is a major reason. Thus, it is a very necessary urgent task to develop new methods and technologies to evaluate the photophysical properties of organic optoelectronic materials and equipment systems. In this project, an on-line research system for photophysical properties is established to detect the intrinsic character of the organic optoelectronic materials and devices, which integrates the fabrication instrument of the film materials and devices with the online measuring equipment combing with the high vacuum technology, the low temperature magnetic field control and the steady state / transient spectrum measurement. The established system not only plays an important promoting role for the theoretical research of organic optoelectronic materials and devices, but also helps improving the research level of organic optoelectronic materials and devices. This research is expected to produce some innovating results with the international advanced level and make contributions to needs of national strategy.

有机光电材料由于其独特的优点，在能源、环境、信息及生物等领域显现出广泛的应用前景。然而，人们对一些影响材料与器件性能的基本光物理过程（如：能量转移、电子转换、电荷分离与复合等）至今缺乏足够清晰的认识，这与该领域对有机光电材料与器件快速增长的需求十分不相适应，已成为制约有机光电材料与器件广泛应用的核心问题之一。其中一个主要原因是目前缺乏必要的有机光电材料光物理特性研究系统与手段，因此，建立针对有机光电材料特点的装备系统，发展新技术与新方法，开展光物理特性研究已成为十分必要与迫切的任务。本项目将高真空技术、低温磁场调控技术和稳态/瞬态光谱检测技术有机结合，建立一套有机光电材料光物理特性评价系统，实现有机光电材料本征光物理性能的表征。该系统的建立不仅对有机光电材料与器件理论研究具有重要的促进作用，同时也将有利于提高我国有机光电材料与器件的研究水平，为满足国家战略需求做出贡献。
