Luminescence of bound excitons created near sodium impurity ions in KCl:Na single crystals
Published 2025-02-01“…The study is focused on luminescence features of bound excitons (exciton-like formations, ELFs) in KCl:Na single crystals created in the field of sodium impurity ions either directly at photoexcitation or via the recombination of electron-hole pairs. The intensity of the X-ray luminescence (XRL) bands peaked at 2.8 and 3.1 eV (emission of recombinationally formed and relaxed ELFs) increases with both, the concentration of sodium impurity ions (10 → 1000 ppm) and the detection temperature (85 → 350 K). …”
