Metasurface-based nanoprinting (meta-nanoprinting) has fully demonstrated its advantages
in ultrahigh-density grayscale/color image recording and display. A typical meta …

Structural colors traditionally refer to colors arising from the interaction of light with structures
with periodicities on the order of the wavelength. Recently, the definition has been …

Polyaniline (PANI), a conductive polymer, is a promising active material for optical switching.
In most studies, active switching has so far been realized only between two states, whereas …

Utilizing electromagnetic hotspots within plasmonic nanogaps is a promising approach to
create ultrasensitive surface-enhanced Raman scattering (SERS) substrates. However, it is …

In this paper, we design a sandwich multilayer film structure based on phase-change
material Ge_2Sb_2Te_5 (GST). In the visible band, based on the amorphous and crystalline …

Nanorings (NRs) with their intrinsic cavities have attracted interest as plasmonic
nanoparticles for years, due to the uniform electric field enhancement inside the cavity, lower …

Here, we report a highly sensitive and reliable surface enhanced Raman scattering (SERS)-
based immunoassay using bimetallic alloy Ag@ Au hollow dual-rim nanorings (DRNs) …

By investigating the relationship between the color saturation and the square nanoblock
period, the plasmonic color filters based on a two-dimensional metal–insulator–metal …

This study represents the synthesis of a novel class of nanoparticles denoted as annular Au
nanotrenches (AANTs). AANTs are engineered to possess embedded, narrow circular …
