The intrinsic exciton transitions of isotopically purified (13C) and natural-abundance (N.A.C) diamond are studied by photoluminescence and transmission spectroscopies at liquid helium temperatures. The comparative study shows that 13C has the same fine structure splitting with N.A.C, indicating that the isotopic effect of diamond does not influence the internal excitonic structure. This approach also deduces the absolute energies of excitons and phonons in 13C and N.A.C at the Δ [k = (0.76, 0, 0) × (2π/a)] point. [ABSTRACT FROM AUTHOR] |
