Stimulated Emission Depletion: STED,Scintillator

In the Stimulated Emission Depletion (STED) phenomenon, the intensity of spontaneous emission from an excited state is logarithmically suppressed as the intensity of the stimulated emission light increases. This behavior serves as indicator of whether a fluorescent material exhibits STED behavior, and a comprehensive understanding of this process is essential for assessing the applicability of the material to STED microscopy and related techniques. In this study, we developed a vacuum optical system which enables time-resolved stimulated emission experiments. Thereby allowing the exploration of previously unreported STED phenomena across a broad wavelength range, spanning from the ultraviolet to the X-ray region.
