FIP Seminar: Advanced Ultrafast Diffuse Reflectance Optical Microscopy-Spectroscopy for Photochemical Analysis at Nanoscale

Ultrafast pump-probe microscopy has been utilized as a promising new ultrafast approach. Transient absorption microscopy a sub-class of pump-probe microscopy enables the localization of the photochemical and photophysical processes in complex systems offering femtosecond timeresolution and sub-micrometer spatial resolution. In comparison, electron-based microscopy methods provide higher spatial resolution. Still, these technologies are typically complex, expensive, and need a high vacuum, which hinders their widespread use for a variety of samples.
