title: Reusable Inorganic Templates for Electrostatic Self-Assembly of Individual Quantum Dots, Nanodiamonds, and Lanthanide-Doped Nanoparticles.
abstract: In this paper, we present an electrostatic self-assembly method for the controlled placement of individual nanoparticle emitters based on reusable inorganic templates. This method can be used to integrate quantum emitters into nanophotonic structures over macroscopic areas and is applicable to a variety of patterning materials and emitter systems. By utilizing surface-charge-mediated self-assembly, highly ordered arrays of nanoparticle emitters were created. To illustrate the broad applicability of this technique, we demonstrate self-assembly using colloidal quantum dots (QD), nitrogen vacancy (NV) centers in diamond nanoparticles, and lanthanide-doped upconversion nanoparticles (UCNP). Placement of single QDs and NV centers was confirmed by performing photon antibunching measurements using a Hanbury-Brown Twiss setup. In addition, template reusability was demonstrated through daily redeposition experiments over a one month period.
