✦ Synopsis

The purpose of the paper is to report the optical absorption and therinoluminescence measurements on IZCl : Ba2+ crystal irradiated with y-rays. Bleaching in F-band increases the glow peak around 7 5 "C and suppresses the 125 "C peak. A similar result is observed in preheat treated crystals. When this peak is thermally cleaned, the broadening of the absorption on the prolonged F-bleached crystals is removed. On the basis of these observations, the glow peak at 75 "C is tentatively attribut,ed to Z,-centers.

Thermoluminescence (TL) of Pr-doped KCI is studied. The influence of pre-heat treatment and optical bleaching of the glow curves and the production of Z, centers are discussed. The glow curves of KC1 containing 1062 ppm of praseodymium (Pr) shows one shoulder at 365 K (TI) and two peaks around 408 K
