Abstract
The absorption, thermostimulated luminescence (TSL) and electron emission (TSE) of prepared and X-irradiated NaCl crystals doped with vanadium were studied. From the TSE-, TSL- and thermo-optical bleaching (TOB-) curves it is suggested that the new 647 nm absorption band and the new TSE- and TSL-peaks at about 480–490 °K are due to Z-centers, i.e. to the aggregates ofF-centers with dipole complexes (divalent vanadium ions and cation vacancies).
