| Abstract | We have prepared cubic boron nitride samples doped with europium and codoped with europium and chromium. Their red photoluminescence is due to Eu3+ and Eu3+-Cr3+ electronic transitions involving Eu3+ in a noncentrosymmetric position in a field of cubic symmetry. Chromium is shown to have a positive effect on the incorporation of Eu3+ into lattice sites of c-BN. The photoluminescence spectrum of polycrystalline c-BN codoped with Eu3+ and Cr3+ is a combination of the spectra of Eu3+ in fields of cubic and monoclinic symmetries, the latter spectrum being blue-shifted relative to the spectrum of Eu3+-doped microcrystalline powder. The c-BN materials prepared in this study can be used as red phosphors and light emitters possessing high thermal stability, radiation hardness, and chemical resistance. |
