Single-photon emitters (SPEs) in 2D semiconductors are usually affected by complex spectral profiles that limit their understanding and applications. Here, the authors combine a noncovalent surface functionalization method with localized mechanical strain to simplify the spectra and enhance the purity of SPEs in monolayer WSe2.
