Thermoluminescence kinetics of lithium borate crystals

The paper reports the results of experimental study and modeling of thermally stimulated recombination processes in undoped crystals of lithium borates Li 2B 4O 7 and LiB 3O 5. For both crystals in the unified experimental conditions, we have measured the glow curves of thermally stimulated luminescence, the spectra and the temperature dependencies of intensity of the steady-state luminescence over the temperature range of 90500 K under X-rays excitation. In the framework of the unified model, we carried out the calculations of the recombination processes and interpretation of the results with the involvement of all the available experimental data on undoped lithium borate crystals. © 2012 Elsevier B.V

Kinetics of thermally stimulated recombination processes in lithium borate crystals

This paper reports on the results of the experimental and theoretical investigations of thermally stimulated recombination processes in crystals of the lithium borates Li 2B 4O 7 and LiB 3O 5. For both types of crystals, the measurements of thermally stimulated luminescence curves, spectra, and temperature dependences of the intensities of steady-state X-ray luminescence have been performed in a single experimental cycle. In the framework of a unified model for the Li 2B 4O 7 and LiB 3O 5 crystals, the thermally stimulated recombination processes have been calculated and the obtained results have been interpreted talking into account all available experimental data. © 2012 Pleiades Publishing, Ltd
