Ultrafast transient absorption spectroscopy
WebSchematic representation of the setup for ultrafast hyperspectral transient absorption spectroscopy with crossed polarization of pump and probe. The system was based on an amplified 800 nm mode-locked Ti:Sapphire laser. A pair of multichannel optical detectors allow for the acquisition of the entire spectrum. Web7 Sep 2024 · Concurrently, ultrafast electron extraction (5 ps) from CsPbI 3 QDs to [SAM]C60 is directly visualized by transient absorption spectroscopy. The results gained here provide an alluring strategy for changing the transportation properties and achieving efficient carrier extraction in CsPbI 3 QDs.

Web25 Oct 2014 · Nice Features of Ultrafast Polarization Spectroscopy It’s as easy to set up as excite-probe (just cross two beams in space and time). It’s almost background-free (crossed polarizers transmit as little as 10-6 of the incident light). Unlike excite-probe, it measures both absorption and phase effects. WebAdditionally, the dynamic range of the spectrometer is so crucial because transient absorption is measured as difference spectra, and the differences can be extremely …
