Abstract
In this study, we design a “fiber-based system” which is using a UV light source with optical fiber to induce UV light through the EDS pole for JEM-2010. Because the TEM chamber must maintain at ultra-high vacuum environment, the sample can only in solid state. In order to observe wet sample in TEM, we use the wet-cell which is designed by our laboratory to prepare samples. Combine the fiber-based system with wet-cell technology let us having the chance to in-situ observes the photo-induced catalysis reaction in EM under nano-scale. We can confirm that the light-induced reaction is actually occurred under OM and TEM by the in-situ movies, difference in the images and the EDS analysis. The result makes sure that our home-make light induced system for TEM is workable.
