| Abstract: | Electronic absorption spectrum of CsBr crystals doped with Hg2+ showed three bands at 340, 250 and 217.5 nm at 300 K, which disappeared on ageing and reappeared on quenching the crystals from 700 K. Radiation damage studies indicated the formation of Hg2+ centres and on prolonged irradiation Hg2+ centres. Similar results have also been obtained in the case of Csl: Hg2+. |
