A beginner-friendly guide to interpreting UV-Vis spectroscopy results, covering key concepts like ?max, absorbance, electronic transitions, and common pitfalls in spectral analysis.

4H-silicon carbide (4H-SiC) is promising for photodetectors (PDs) capable of operating at high voltages and elevated temperatures. However, the wide bandgap of 4H-SiC (3.26 eV) restricts its ...

Surface-enhanced Raman scattering (SERS) spectra of Iron Gall Inks are reported here for the first time. These inks were prepared by different methods varying their basic ingredients: tannic acid (TA) ...

However, the samples with the novel low viscosity zinc oxide, iron oxides and erioglaucine blocked almost over 90% of ultraviolet, visible light and near-infrared. It can be concluded that this novel ...

“We believe that our scheme to create an intense four-octave-spanning UV-Vis-IR full-spectrum femtosecond laser source by harnessing the synergic action of 2nd-NL HHG and 3rd-NL SPM effects ...

Team led by Professor Junsuk Rho creates metasurface polarizer that generates and detects vortex beams across both ultraviolet and visible light, expanding possibilities for optical technologies.

Ultraviolet (UV) light has higher energy photons than visible light and, thus, has more applications. Tokyo Tech researchers have now developed a brilliant innovation—a solid-state material that can ...
