| dc.description | Radioluminescence of CsI(CO3) crystal is caused by radiative annihilation of the perturbed two-halogen excitons of two types, which are located in nearby impurity-vacancy dipole [CO32- -va+] anion sites. The excitons arise due to electron tunneling from F to Vk centers originated by thermal liberation of holes captured by CO32- - ions under irradiation. The formation process of CO32- -perturbed excitons is responsible for post-radiation rise of the luminescence pulse and the tunnel recombination in the short-interspace donor-acceptor pairs [F,Vk] causes the exponential decay of the luminescence pulse. | ru_RU |
| dc.description.abstract | The spectral-kinetics characteristics of short-living absorption and luminescence induced by an electron pulse irradiation in CsI(CO3) crystal are studied. It is shown that the scintillation pulse of CsI(CO3) crystal is caused by the radiative annihilation of perturbed two-halogen excitons of two types, which are located in nearby impurity-vacancy dipole [CO32- -va+] anion sites. The processes responsible for post-radiation rise and decay of both CO32- -related luminescence bands with maxima at 2.8 and 3.2 eV are monomolecular with the thermal activation energy Erise=0.1 eV and Edecay= 0.05 eV. The cathodoluminescence pulse kinetics is discussed in the terms of the thermally assistant release of holes captured by CO32- -ions and the formation of CO32- -perturbed two-halide excitons. | ru_RU |
