Low-temperature creation of Frenkel defects via hot electron-hole recombination in highly pure NaCl single crystals
The creation spectrum of stable F centres (being part of F-H pairs of Frenkel defects) by synchrotron radiation of 7–40 eV has been measured for highly pure NaCl single crystals at 12 K using a highly sensitive luminescent method. It is shown that the efficiency of F centre creation in a closely pac...
