## Description

- description: Quantum light sources, especially single-photon emitters, are pivotal
    for advancing quantum technologies. Despite extensive studies, the emission from
    detects-localized excitons in monolayer WSe2 under external perturbations, such
    as magnetic fields, remains underexplored. Herein, we investigate the physical
    nature and dynamics of defect-localized excitons under in-plane magnetic fields
    using steady-state and time-resolved photoluminescence (PL) spectroscopy. Our
    observations reveal a sharp PL peak indicative of single-photon emission, comprising
    doublet peaks from excitons with hybridized spin states. Notably, magnetic brightening
    of the PL peak was detected in a small magnetic field below 1 T, and the dynamics
    of localized excitons in the hybridized states under magnetic fields show the
    field-induced mixing of two states, which determines the magnetic brightening
    phenomena. These insights pave the way for tunable single-photon emitters manipulated
    by external magnetic fields, heralding advances in quantum optics applications.
