Abstract
The efficiency study of thermoluminescence light sum storage in NaCl : Ag crystals by ultrasoft X-ray irradiation (quantum energy range 60–240 eV) is reported. It is shown that the storage process is strongly affected by the surface energy losses mainly due to the migration of hot electron-hole pairs from the depth of about 10 -5 cm to the surface. To a good approximation the hot carriers migration may be described as a diffusion process with high surface recombination velocity. The resonant X-ray photoelectrons effectively create low-energy excitons which interact with Ag + centres more effectively than hot electron-hole pairs. The Cl -L 2,3 X-ray excitons are identified through specific decay products.
