Since flux growth inevitably introduces flux inclusions, synthesized polycrystalline EuAl 3 (BO 3 ) 4 could act as a better path to highquality crystals. Despite research spanning decades, flux-free synthesis of polycrystalline EuAl 3 (BO 3 ) 4 has been reported only once for Cr-doped samples and once for Gd-and Ydoped samples. There is no clear evidence that an undoped, phase-pure sample has been prepared as both reports lack XRD data.
