Thermoluminescence of CsCl:NO3- crystals irradiated by X-rays at room
temperature has been studied. The presence of nitrate impurity was con
firmed through optical absorption measurements. Nitrate-doped crystals
exhibit two glow peaks centered at 361 and 401 K with a warming rate
of 60 K min-1 and analysis indicates first order kinetics with activat
ion energies 0.91 and 1.02 eV respectively. The first peak (361 K) ori
ginates from F centers and the 401 K peak from nitrate impurity in the
host matrix.
