“…[97] This electrostatic assembly method could be further developed to enable the on-demand positioning of NDs at any desired location by applying a high-voltage electric field through an AFM nanotip, favoring highly efficient site-specific particle assembly, as shown in Figure 6e. [98,99] The number of particles assembled depended on the injection voltage at the trapping location, increasing linearly with the applied voltage. Additionally, pulsed DC voltage could be used to eject sub-attoliter volume droplets from a nanopipette containing NDs, which rapidly evaporated upon landing on the substrate, thereby printing the NDs.…”

Nitrogen vacancy (NV) centers in diamonds are of current interest as quantum sensors, single photon sources, and biological nanomaterials due to their unique optical and spin properties, biocompatibility, and robust structure. Though NV center in diamonds demonstrates longer coherence time and has been used for more sensing and quantum operations compared to nanodiamonds (NDs), the prospect of selecting NDs with single, few, or multiple NV centers and moving the NDs to the location of interest makes NDs suitable for various applications, due to which there is a significant boost in the last decade to manipulate and position the NDs on the surface or to achieve dynamic control in the fluidic environment. This work covers some of the basics of the materials and optical properties of nanodiamonds and discusses the capabilities and challenges for practical applications, followed by a detailed review of the various static and dynamic manipulation methods of nanodiamonds in microfluidic environments (colloidal NDs).

Light emission of europium (Eu3+) ions placed in the vicinity of optically resonant nanoantennas is usually controlled by tailoring the local density of photon states (LDOS). We show that the polarization and shape of the excitation beam can also be used to manipulate light emission, as azimuthally or radially polarized cylindrical vector beam offers to spatially shape the electric and magnetic fields, in addition to the effect of silicon nanorings (Si-NRs) used as nanoantennas. The photoluminescence (PL) mappings of the Eu3+ transitions and the Si phonon mappings are strongly dependent of both the excitation beam and the Si-NR dimensions. The experimental results of Raman scattering and photoluminescence are confirmed by numerical simulations of the near-field intensity in the Si nanoantenna and in the Eu3+-doped film, respectively. The branching ratios obtained from the experimental PL maps also reveal a redistribution of the electric and magnetic emission channels. Our results show that it could be possible to spatially control both electric and magnetic dipolar emission of Eu3+ ions by switching the laser beam polarization, hence the near field at the excitation wavelength, and the electric and magnetic LDOS at the emission wavelength. This paves the way for optimized geometries taking advantage of both excitation and emission processes.

Nanofabrication technologies significantly influence the development of modern optical science. One of such technologies is laser‐induced transfer, which allows the creation of single Mie‐resonant spherical particles on a wide range of substrates. This study shows that this method can provide asymmetric dimers at the output: a single femtosecond pulse being focused on a silicon‐on‐insulator wafer results in appearing two nearly spherical particles of different sizes. The resulting dimers are characterized by scanning electron microscopy, elastic light scattering and Raman spectroscopy to gain insight into their structural properties. Back focal plane imaging and variable‐color evanescent‐wave illumination are then employed to measure the light scattering patterns from isolated dimers. Due to the interference of the excited resonances, the observed patterns are strongly asymmetric in a range of visible wavelengths, which is consistent with theoretical predictions. The results demonstrate the potential of asymmetric silicon dimers made by single‐shot laser‐induced transfer for color routing at visible light.

Large-scale controlled coupling of single-photon emitters to high-index dielectric nanoantennas by AFM nanoxerography

Abstract: Large-scale coupling of nanodiamonds hosting NV centers to silicon dimer nanoantennas was achieved by AFM nanoxerography. This controlled process, yielding configurations down to a single deposited quantum emitter, leads to their enhanced brightness.
