It is shown that first room temperature, and ultrabright single photon emission from a color center in two-dimensional multilayer hexagonal boron nitride means that vacancy-related centers are a likely source of the emission.
Identifying carbon as the source of visible single-photon emission from hexagonal boron nitride
Comparison of hexagonal boron nitride samples grown with different techniques and with varying carbon-doping content provides evidence that the defects emitting single photons in the visible range are carbon related.
Robust multicolor single photon emission from point defects in hexagonal boron nitride
We demonstrates engineering of quantum emitters in hBN multi-layers using either electron beam irradiation or annealing. The defects exhibit a broad range of multicolor room-temperature single photon…
Initialization and read-out of intrinsic spin defects in a van der Waals crystal at room temperature
An ensemble of spins associated with an intrinsic defect of two-dimensional hexagonal boron nitride is shown to be optically addressable, allowing spin polarization of its triplet ground state and providing evidence of spin coherence.
Multi-photon near-infrared emission saturation nanoscopy using upconversion nanoparticles
It is reported that upconversion nanoparticles (UCNPs) can unlock a new mode of near-infrared emission saturation (NIRES) nanoscopy for deep tissue super-resolution imaging with excitation intensity several orders of magnitude lower than that required by conventional MPM dyes.
Engineering and Tuning of Quantum Emitters in Few-Layer Hexagonal Boron Nitride.
Chemical vapor deposition growth of large-area, few-layer hBN films that host large quantities of SPEs are demonstrated and tuning of the ZPL wavelength using ionic liquid devices over a spectral range of up to 15 nm-the largest obtained to date from any solid-state SPE.
Room Temperature Initialisation and Readout of Intrinsic Spin Defects in a Van der Waals Crystal
Optically addressable spins in wide-bandgap semiconductors have become one of the most prominent platforms for exploring fundamental quantum phenomena. While several candidates in 3D crystals…
