Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview01:02

Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview

7.7K
Ultraviolet–visible (UV–visible or UV–Vis) spectroscopy is an analytical technique that investigates the interaction between matter and UV–Vis light within the electromagnetic spectrum. This method is widely used for its versatility, simplicity, and relatively quick data acquisition, making it valuable for both qualitative and quantitative analysis. When UV–Vis radiation passes through a material,  molecules absorb light depending on the energy required for...

Super-resolution Fluorescence Microscopy

12.2K
Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been...

Main Methods:

  • Fabrication of a diamond-based vectorial metasurface platform.
  • Experimental demonstration of a broadband geometric-phase meta-hologram.
  • Development of multisegment and polarization-multiplexed DUV meta-holograms.

Main Results:

  • Achieved continuous holographic imaging from visible to DUV spectrum.
  • Demonstrated tailored polarization distributions in DUV holograms.
  • Showcased polarization-multiplexed DUV meta-holograms.

Conclusions:

  • Diamond metasurfaces enable ultrabroadband vectorial holography, overcoming spectral constraints.
  • Diamond's properties (DUV transparency, high damage threshold) make it suitable for extreme conditions.
  • This platform facilitates applications in optical storage, secure communications, and UV encryption.
