超高真空荧光显微分子生长特性监测系统

Molecular growth investigation system using fluorescence microscopy in ultra-high vacuum environment

将荧光显微术耦合进有机分子外延薄膜生长的超高真空之中,研制出可变温实时原位荧光显微分子生长特性监测系统。该系统将衬底/样品变温模块,快速衬底/样品装卸载结构和荧光显微术融合一体,利用自行开发的实时监测分子生长软件,可以对超高真空环境下有机分子生长实验进行基于荧光图像的形貌特性动态研究。这对于表面有机分子生长表面动力学特性分析具有重要的实践意义和科学意义。

To investigate the dynamic process of molecular growth on insulating surface, a variable temperature ultra- high vacuum system was built ,which couples the fluorescence microscopy technique with the vacuum chamber and is used for epitaxial growth of organic molecule thin films. The system integrates substrate/sample temperature control module, fast substrate/sample loading and unloading mechanism and fluorescence microscopy together. Using the self- developed real time monitoring molecular growth software, the fluorescence images can be captured in the process of organic molecular growth. The real-time and in-situ investigation ability of such an instrument renders it very suitable and powerful for the studies of molecular growth kinetics on surface.
