Our research group has investigated Discretized Hexagonal Boron Nitride Quantum Emitters and Their Chemical Interconversion. We focus on quantum emitters in two-dimensional hexagonal boron nitride (hBN), known for their unique photophysical properties and promising applications in quantum computing and communications. Despite the wide range of emission energies from hBN defects, identifying and modulating specific emitters remain challenging. Our work involves collecting over 2000 spectra of single, isolated zero-phonon lines (ZPLs) and organizing them into seven discretized emission energies. We have developed two chemical processing schemes based on water and boric acid etching that generate or preferentially interconvert specific emitters. These findings significantly advance the understanding of solid-state chemistry and photophysics of hBN quantum emission.
