## Description

- description: 'Optically active defects in wide bandgap materials play a central
    role in several emerging applications in quantum information and sensing, as they
    allow for manipulating and harvesting the internal electronic degrees of freedom
    with optical means. Interactions among defects and with the surrounding environment
    represent crucial features for sensing but can severely hamper the coherence of
    the quantum states and prevent an efficient integration with photonic architectures
    due to unpredictable spectral instability. Understanding and controlling defective
    interactions would mitigate the effects of spectral instabilities and enable quantum
    applications based on long-range interactions. Here, we investigate the photoluminescence
    spectral dynamics of quantum emitters in defective hexagonal boron nitride (hBN),
    a material whose emission spectrum notoriously displays spectral wandering and
    diffusion, and we identify several optical transitions with discrete energy jumps.
    By analyzing the spectral dynamics of defective hBN, we can associate the spectral
    jumps with the interplay amid competing recombination pathways available to the
    defect states in a process like donor-acceptor-pairs (DAP). The discrete spectral
    jumps observed in the emission spectrum of hBN arise from interactions between
    the harmonic states of nitrogen π orbitals of delocalized defects, and their energy
    can be ascribed to a DAP-like transition sequence. Our results allow mapping of
    the defect geometry in a hBN lattice, setting a basis for controlling and mitigating
    the spectral jumping in this platform, and paving the way toward using long-range
    interactions of defect ensembles for quantum technology. '
