Research related to the development and application of luminescent nanoparticles (LNPs)
for chemical and biological analysis and imaging is flourishing. Novel materials and new …

Essentially, the term aerogel describes a special geometric structure of matter. It is neither
limited to any material nor to any synthesis procedure. Hence, the possible variety of …

Previously unwelcome, defects are emerging as a new frontier of research, providing a
molecular focal point to study the coupling of electrons, excitons, phonons and spin in low …

Efficient light-matter interaction lies at the heart of many emerging technologies that seek on-
chip integration of solid-state photonic systems. Plasmonic waveguides, which guide the …

Single-photon sources and their optical spin readout are at the core of applications in
quantum communication, quantum computation, and quantum sensing. Their integration in …

A study of the photophysical properties of nitrogen-vacancy (NV) color centers in diamond
nanocrystals of size 50 nm or below is carried out by means of second-order time-intensity …

Optical microcavities are a powerful tool for enhancing the fluorescence of individual
quantum emitters. However, the broad emission spectra encountered in the solid state at …

The photoluminescence (PL) arising from silicon carbide nanoparticles has so far been
associated with the quantum confinement effect or to radiative transitions between …

Fluorescence lifetime experiments are a standard approach for measuring excited-state
dynamics and local environmental effects. Here, we show that entangled photon pairs …

We suggest a novel class of active nanoantennas based on diamond nanoparticles with
embedded nitrogen-vacancy centres coupled to Mie resonances of nanoparticles. We …
