Surface nanostructuring enables the fabrication of materials with highly desirable properties. Nanostructured tungsten surfaces have potential applications in solar water splitting. Exposing a polished surface to helium plasma induces various morphological changes. Depending on ion energy, temperature, and fluence, clusters, bubbles foam-like nanostructures develop surface. In this study, were ...

Dielectric stack interference ® lters can be used in conjunction with a high-throughput single-stage spectrograph to facilitate the measurement of high signal-to-noise (S/N) ultraviolet (UV) Raman spectra with 228.9-nm and 244-nm excitation wavelengths. Placed between the sample and the spectrograph, these ® lters re ̄ ect Rayleigh scattering while transmitting Stokes-shifted Raman scattering. W...
