Colloidal self-assembly refers to a solution-processed assembly of nanometer-/micrometer-
sized, well-dispersed particles into secondary structures, whose collective properties are …

Plasmonic colours are structural colours that emerge from resonant interactions between
light and metallic nanostructures. The engineering of plasmonic colours is a promising …

In this Letter, we experimentally report an achromatic metalens (AML) operating over a
continuous bandwidth in the visible. This is accomplished via dispersion engineering of …

Plasmonic colour printing based on engineered metasurfaces has revolutionized colour
display science due to its unprecedented subwavelength resolution and high-density optical …

Metal nanoparticles are excellent light absorbers. The absorption processes create highly
excited electron–hole pairs, and recently there has been interest in harnessing these hot …

The colour gamut, a two-dimensional (2D) colour space primarily comprising hue and
saturation (HS), lays the most important foundation for the colour display and printing …

All forms of light manipulation rely on light–matter interaction, the primary mechanism of
which is the modulation of its electromagnetic fields by the localized electromagnetic fields …

We report a phase-modulated multicolor meta-hologram (MCMH) that is polarization-
dependent and capable of producing images in three primary colors. The MCMH structure is …

Localized optical resonances in metallic nanostructures have been increasingly used in
color printing, demonstrating unprecedented resolution but limited in color gamut. Here, we …

Colour generation by plasmonic nanostructures, and metasurfaces, has several advantages
over dye technology: reduced pixel area, sub-wavelength resolution and the production of …
