Tip-enhanced Raman scattering (TERS) is one of the few methods to access the molecular
composition and structure of surfaces with extreme lateral and depth resolution, down to the …

Over the past two decades, coherent multidimensional spectroscopies have been
implemented across the terahertz, infrared, visible, and ultraviolet regions of the …

Near-field scanning optical microscopy (NSOM) is a super-resolution optical microscopy
based on nanometrically small near-field light at a metallic tip. It can be combined with …

Nanofocusing of electromagnetic (EM) energy is an emblematic effect that guides EM
energy along plasmonic conical structures, effectively focusing it at its nanometer‐sized …

Plasmonic graded nano-gratings enable rainbow trapping of multiple resonant modes over
a wide wavelength spectrum, useful for multi-channel Surface Enhanced Raman …

This chapter covers state-of-the-art development and results in tip-enhanced Raman
spectroscopy (TERS) as a significant configuration of near-field nanospectroscopy. The …

One of the most important issues after synthesizing colloidal quantum dot nanoparticles is
how to use them. In some cases, a very small number of these nanoparticles is needed. One …

Photochromic coatings of silver-doped titania were swiftly synthesized on glass substrates
through a two-step methodology. The titania gels were first synthesized using the sol-gel …

Abstract Tip-Enhanced Raman Scattering (TERS) has emerged as a revolutionary technique
capable of probing matter at the nanoscale, offering unprecedented spatial resolution and …

The plasmon nanofocusing process has been widely implemented in near-field scanning
optical microscopy (NSOM) recently because it allows generating a background-free …
