We have synthesized heteroatom-doped rhombohedral boron sulfide (r-BS) to investigate how heteroatom incorporation affects its crystal structure and optical properties. The samples were prepared under 5.5 GPa and 1873 K, with varying heteroatom content while keeping the molar ratio B:(S+heteroatom) = 1:1. X-ray diffraction revealed peak shifts in specific planes, suggesting lattice changes caused by heteroatom doping. Excitation– emission matrix (EEM) spectroscopy showed new fluorescence responses in the heteroatom-doped samples not observed in undoped r-BS, even at room temperature. These findings suggest the formation of new emission centers, likely due to local structural distortions or changes in the electronic band structure
