Abstract

Ultraviolet (UV) and deep-ultraviolet (DUV) cover an interesting spectral range where short wavelength and high photon energy can lead to new information in microscopy and spectroscopy as well as to improved applications of photocatalytic effects, solar cells and lithography. While short wavelength can intrinsically lead to better spatial resolution in microscopy, an inclusion of plasmonic effects in UV-DUV can result in much higher spatial resolution in microscopy and nanoscopy than what we expect in the visible range. However, even though the advantages of the UV-DUV spectral range have been recognized for a long time, there has been only limited effort to explore the plasmonics in DUV towards its applications in spectroscopy at nanoscale, in high-resolution microscopy, and in many other related fields.
