[摘要]：The kinetics of electron tunneling between electron and hole sites, stimulated by mobility of lithium cations in lithium gadolinium orthoborate (Li6Gd(BO3)(3)) crystals has been studied. A mathematical model has been proposed to describe the kinetics in the wide time interval of 10(-8)-100 s after pulsed irradiation. The calculation results have been compared with experimental data on the decay kinetics of transient optical absorption (TOA) in Li6Gd(BO3)(3) crystals in the visible and UV spectral regions. The nature of radiation defects responsible for TOA is discussed, as well as the dependence of the TOA kinetics on temperature, excitation power, and other experimental conditions. |
