✦ Synopsis

Influence of the Aggregation State of Sr2+ Ions on Glow Curves Behaviour of NaCl: Sr2+

Glow curves were recorded for NaCl : Sr2+ crystals subjected to annealing and quenehing from elevated temperatures. These specimens were irradiated with X-rays at room temperature by tungsten target. Samples exhibit certain glow peaks which are observed only in the first thermal cycle. A marked difference in the glow curves pattern for first and subsequent thermal cycles has been observed. It is suggested that these changes may be due to the change in configurational coordinate system of F-centre due to impurity existing different states. This idea is supported by optical microscopy studies.

Thermoluminescence (TL) and Optical absorption studies are carried out to study the bleaching kinetics of F-centre and formation of Z,-centres in X-irradiated strontium doped NaCl crystals, both in as-grown state and in quenched state. An additional TL peak is observed in this crystal system after F
