Photoluminescence of boron carbide

The excitation of B 4.3C with an Ar-laser ( ℏω=2.4 eV ) yields a photoluminescence spectrum between about 1.56 and 1.58 eV with its main maximum at 1.563 eV and a weaker maximum at 1.572 eV. It is attributed to the indirect-allowed recombination of free excitons.
