Impurity do** is a promising method to impart new properties to various materials. Due to
their unique optical, magnetic, and electrical properties, rare-earth ions have been …

The attractive features of lanthanide-doped upconversion luminescence (UCL), such as high
photostability, nonphotobleaching or photoblinking, and large anti-Stokes shift, have shown …

This Review focuses on the integration of plasmonic and dielectric metasurfaces with
emissive or stimuli-responsive materials for manipulating light–matter interactions at the …

Avalanche phenomena use steeply nonlinear dynamics to generate disproportionately large
responses from small perturbations, and are found in a multitude of events and materials …

Ten years ago, three teams experimentally demonstrated the first spasers, or plasmonic
nanolasers, after the spaser concept was first proposed theoretically in 2003. An overview of …

Engineering nanostructures with exceptionally high-Q resonances mediated by the Fano-
type hybridization between discrete states associated with the periodicity of the structure and …

Subwavelength confinement of light with plasmonics is promising for nanophotonics and
optoelectronics. However, it is nontrivial to obtain narrow plasmonic resonances due to the …

The vast development of nanofabrication has spurred recent progress for the manipulation
of light down to a region much smaller than the wavelength. Metallic plasmonic array …

Superposing two or more periodic structures to form moiré patterns is emerging as a
promising platform to confine and manipulate light. However, moiré-facilitated interactions …
