The luminescence of KBr crystals containing KI of various concentrations between 0 and 100 mole % under X-ray irradiation and UV illumination has been investegated at liquid helium temperature. The two characteristic emission bands are observed at about 3.50eV and 4.30eV. The former band at 3.50eV is shown to originate from the recombination of an electron with the self-trapped hole of the complex V_k-center, IBr- and π-polarized with a degree of polarization P=-0.15±0.03. From the excitation spectra for this band by UV illumination, a possibility of energy transfer between excited Br- ions and I- ions is discussed. The latter band at 4.30eV is due to a Br- ions and I- ions is discussed. The latter band at 4.30eV is due to a cluster of I- ions.
