Rare earth doped upconversion nanocrystals (RE-UCNCs) have attracted extensive
interests owing to their unique physical properties and great potential applications in bio …

The assembly of inorganic nanoparticles often leads to collective properties that are different
from the combined properties of the individual components. In particular, coupling plasmonic …

Plasmonic dimer nanoantennas are characterized by a strong enhancement of the optical
field, leading to large nonlinear effects. The third harmonic emission spectrum thus depends …

For the purpose of using plasmonics in an integrated scheme where single emitters can be
probed efficiently, we experimentally and theoretically study the scattering properties of …

We propose a broad-band near-infrared trapezoidal plasmonic nanoantenna, analyze it
numerically using finite integration and difference time domain techniques, and explain …

In the current study, we report on the deterministic fabrication of solid immersion lenses
(SILs) on lithographically pre-selected semiconductor quantum dots (QDs). We demonstrate …

Substituting noble metals for high-index dielectrics has recently been proposed as an
alternative strategy in nanophotonics to design broadband optical resonators and …

Very low density growth of GaAs quantum dots in self-assembled nanoholes created by
gallium droplet etching is demonstrated. The emission energy of the quantum dots can be …

We report on the structural and optical properties of individual bowtie nanoantennas both on
glass and semiconducting GaAs substrates. The antennas on glass (GaAs) are shown to be …

We investigate the multiphoton photoluminescence characteristics of gold nanoantennas
fabricated from single crystals and polycrystalline films. By exciting these nanostructures …
