Luminescence investigations of cubic boron nitride doped with beryllium

Formation of flower-like MgO crystal and its effect on the photoluminescence of Mg-cBN ceramics

“…For examples, cBN can be used in active and passive elements of integrated circuits, surface acoustic wave devices, various detectors, heat-conducting substrates, cold emitters, etc. However, practical applications of cubic boron nitride have been complicated by the absence of large-sized crystals and high-quality single-phase thin films [11].…”
