All forms of energy follow the law of conservation of energy, by which they can be neither
created nor destroyed. Light-to-heat conversion as a traditional yet constantly evolving …

All-dielectric metamaterials and metasurfaces have been demonstrated as ideal platforms to
manipulate electromagnetic waves and enhance light–matter interaction. Analogous to …

The growing interest to develop modern digital displays and colour printing has driven the
advancement of colouration technologies with remarkable speed. In particular, metasurface …

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

Let there be light–to change the world we want to be! Over the past several decades, and
ever since the birth of the first laser, mankind has witnessed the development of the science …

Optical metasurfaces—subwavelength-patterned surfaces that interact strongly with light—
have been an active area of research for more than a decade. The field has been driven by …

Optically variable devices (OVDs) are in tremendous demand as optical indicators against
