X-ray and thermoluminescence of LiKB4O7 single crystals
چکیده انگلیسی
The thermoluminescent (TL) and X-ray luminescent (XL) spectra of undoped LiKB4O7 (LKBO) single crystals had been investigated in the temperature range 80-300 K. It was found that in LKBO crystals, there are two intensive TL peaks at 112 and 132 K. The only one band emission spectra of sharply defined Gaussian shape, confirming the same mechanism of XL and TL by the radiation annihilation of the strongly localized self-trapped excitons (STE), had been observed in the TL and XL spectra. The possible models of these localization centers STE have been discussed.
