Colloidal noble metal nanoparticles (NPs) are composed of metal cores and organic or
inorganic ligand shells. These NPs support size‐and shape‐dependent plasmonic …

Metamaterials are artificial electromagnetic media structured on the subwavelength scale for
controlling the propagation of waves by means of transformation optics. The research activity …

It is commonly believed that the most efficient way to pack a finite number of equal-sized
spheres is by arranging them tightly in a cluster. However, mathematicians have conjectured …

The optical properties of 3D metacrystals made of gold nanoparticles in protein nanocages
are studied. These metacrystals have sizes of tens of micrometers and are of high structural …

Biologically inspired superstructural materials exhibit wide application prospects in many
fields, in terms of mitigating increasingly serious electromagnetic (EM) pollution in the civil …

Nanoparticle superlattices produced with controllable interparticle gap distances down to
the subnanometer range are of superior significance for applications in electronic and …

Using the trapped rainbow effect to slow down or even stop light has been widely studied.
However, high loss and energy leakage severely limited the development of rainbow …

This study demonstrates the developments of self‐assembled optical metasurfaces to
overcome inherent limitations in polarization density (P) and high refractive indices (n) within …

Sacrificial methods using polystyrene (PS) templates are extensively applied in various
research fields, particularly for fabricating gas sensors. The many processing advantages of …

Monodispersed microspheres play a major role in optical science and engineering,
