Wavelength-Dependent Nonlinear Absorption in Palladium Nanoparticles
Applied Sciences (Switzerland), 2021 This paper aims to study the nonlinear absorption characteristics of palladium nanoparticles (PdNPs) at off-resonant wavelengths. For this purpose, multi-wavelength (500–650 nm) nanosecond Z-scan technique was used. The experimental results indicate that

Wavelength-Dependent Features of Photoelectron Spectra From Nanotip Photoemission
Photonics, 2020 If a metal nanotip is irradiated with the light of a wavelength much larger than the nanotip’s radius of curvature, optical near-fields become excited.

Excitation Wavelength-Dependent Photochemistry
PhotochemThe dependence of photochemistry on excitation wavelength is not a recently observed phenomenon; nonetheless, it has, surprisingly enough, been largely ignored in the field.

Wavelength-Dependent Three-Dimensional Volumetric Optical Vortices Modulation Based on Metasurface
IEEE Photonics Journal, 2018 The emergence of the metasurface has spawned an ultrathin, compact, and planner way to generate the orbital angular momentum (OAM) beam array. Several types of OAM beam array generators based on the metasurface have been reported, however, most of them ...

Wavelength dependent excited state dynamics observed in canonical pyrimidine nucleosides
Journal of Photochemistry and Photobiology, 2023 Epidemiological evidence indicates that damage to DNA/RNA initialized by ultraviolet (UV) radiation is associated with skin cancer. Wavelength dependence of DNA photodamage was proposed as early as 1990s and demonstrated later on.
