Abstract
Optical absorption, thermoluminescence and thermoluminescence emission of nickel-doped CsCl crystals are measured. The presence of nickel in the host matrix has been confirmed by two absorption bands observed a t 225 and 246 nm. Among the four glow peaks observed at 341, 363, 378 and 396 K the former three are attributed to thermal decay of F center s and the latter to F centers in the vicinity of nickel impurity. F bl eaching does not produce any Z type centers.
