Abstract
- The luminescence of Cu+ and Cu2+ ions in CsBr:Cu and CsBr:CuBr2 crystals, respectively, is investigated under excitation by synchrotron radiation in the CsBr fundamental absorption range at 10 K and 300 K. The existence of the luminescence bands of different origin: (i) the intrinsic radiative transition of Cu+ ions in the bands peaked at 2.61 eV and 2.23 eV, (ii) the recombination luminescence of Cu2+ ions in the bands peaked at 2.55 eV and 2.13 eV, (iii) the luminescence of excitons localized around Cu+ and Cu2+ ions in the band peaked at 3.08 eV and 3.38 eV, respectively, was found in CsBr:Cu and CsBr:CuBr2 crystals. The energies of creation of exciton localized around Cu+ and Cu2+ ions (6.06 eV and 6.09 eV, respectively, at 10 K) and excitons bound with these ions (5.83 eV and 5.99 eV at 300 K) were determined as well.
