## Description

- description: We offer direct evidence that hBN SPEs generated through annealing
    are not inside the hBN itself but originate from organic residues that carbonize
    and form aromatic fluorophores. Nanoscale Fourier transform infrared spectroscopy
    is used to analyze the emission sites, revealing the presence of carbon bonds
    in aromatic rings with a characteristic C═C absorption peak at 1650 cm–1. These
    emitters are primarily located in encapsulated areas of the hBN flake rather than
    uniformly distributed within the lattice. This finding opens the door to designing
    stable and reliable SPEs, enabling their integration into the rapidly growing
    quantum photonics applications.
