Single photon emitters (SPEs) in hexagonal boron nitride (hBN) are promising candidates for quantum light generation. Despite this, techniques to control the formation of hBN SPEs down to the monolayer limit are yet to be demonstrated. Recent experimental and theoretical investigations have suggested that the visible wavelength single photon emitters in hBN originate from carbon-related defects. Here we demonstrate a simple strategy for controlling SPE creation during the chemical vapor…

Selective Defect Formation in Hexagonal Boron Nitride
Luminescent defect-centers in hexagonal boron nitride (hBN) have emerged as a promising 2D-source of single photon emitters (SPEs) due to their high brightness and robust operation at room
Engineering and Tuning of Quantum Emitters in Few-Layer Hexagonal Boron Nitride.
TLDR
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.
Stark Tuning of Single-Photon Emitters in Hexagonal Boron Nitride.
TLDR
By fabricating van der Waals heterostructures of h-BN and graphene, this work demonstrates the electrical control of single-photon emission from atomic defect emitters via the Stark effect and found field-induced discrete modification and stabilization of emission intensity, which were reversibly controllable with an external electric field.
Grain Dependent Growth of Bright Quantum Emitters in Hexagonal Boron Nitride
Point defects in hexagonal boron nitride have emerged as a promising quantum light source due to their bright and photostable room temperature emission. In this work, we study the incorporation of
Single-photon emission from two-dimensional hexagonal boron nitride annealed in a carbon-rich environment
For quantum photonic applications, such as quantum communication, optical quantum information processing, and metrology, solid-state sources of single-photon emitters are highly needed. Recently,
Electrically tunable quantum emitters in an ultrathin graphene–hexagonal boron nitride van der Waals heterostructure
We explore the photoluminescence (PL) properties of hexagonal boron nitride (h-BN) quantum emitters embedded within atomically thin graphene/h-BN heterostructures fabricated by mechanical transfer.
Midgap radiative centers in carbon-enriched hexagonal boron nitride
TLDR
It is demonstrated that enriching hBN with carbon (C) activates an optical response of this material in the form of a series of well-defined resonances in visible and near-infrared regions, which appear in the luminescence spectra measured under below-bandgap excitation.
Spectrally Resolved Photodynamics of Individual Emitters in Large-Area Monolayers of Hexagonal Boron Nitride.
TLDR
These results show that high control over h-BN growth and treatment can produce a narrow distribution of emitter type and that surface interactions heavily influence the photodynamics, and highlight the utility of spectrally resolved wide-field microscopy in the study of optically active excitations in atomically thin two-dimensional materials.
Extrinsic Effects on the Optical Properties of Surface Color Defects Generated in Hexagonal Boron Nitride Nanosheets
TLDR
It is found that subsequent ozone treatments of the deposited hBN nanosheets improve the optical emission properties of created defects, as revealed by their zero-phonon linewidth narrowing and reduction of background emission.
