Abstract
The luminescence spectra of B4.3C, B6.5C and B10C boron carbide with different isotope enrichments (10B, 11B, 12C, 13C) yield electron transition energies from gap states into the valence band and between localized levels in the gap with 0.25 meV resolution. The results well agree with the actual band scheme derived from optical absorption, electrical properties and interband luminescence. Within the whole homogeneity range, the transition energies are independent of chemical composition and isotopes.Keywords
