Attosecond transient absorption spectroscopy (ATAS) is an advanced technique that enables the direct observation of electron dynamics on the attosecond (10⁻¹⁸ second) timescale. By utilising isolated ...

Ultrafast extreme ultraviolet (XUV) spectroscopy is a powerful technique for probing the dynamics of atoms and molecules with attosecond time resolution. However, conventional XUV absorption ...

Charge-carrier traps play a central role in the excited-state dynamics of semiconductor nanocrystals, but their influence is often difficult to measure directly. In CdS and CdSe nanorods of nonuniform ...

The top panel illustrates halide substitution in cesium lead halide (CsPb(Br/Cl)₃) nanocrystals, where photoirradiation induces exchange between bromide and chloride ions, altering the Br/Cl ratio.

The sample generates the capacitance transient, which is then measured by the instrument. A temperature sweep is applied while employing a lock-in technique. Subsequently, the instrument filters out ...

A photosensitizer (PS) is a chemical species that initiates a reaction upon absorption of light. Although the chemical compositions and practical applications of PS' differ widely, they all follow the ...

A team at the Institute for Basic Science (IBS) Center for Molecular Spectroscopy and Dynamics (CMSD) has developed a new spectroscopic technique to monitor changes in perovskite nanomaterials in real ...

Why is Diffuse Reflectance Spectroscopy Used? One of the main techniques for evaluating the optical properties of materials is optical absorption spectroscopy, or UV-vis spectroscopy. Most absorption ...
