Abstract

The formation of color centers at LNT (measured after warming to RT) in {A figure is presented} - irradiated KC1 crystals doped with Eu(2+) ions in a wide concentration range is studied by optical absorption, emission and the ITC method. No effect of post-irradiation warming up to RT on Eu(2+)-dipole concentration is observed. The ITC measurements reveal the drastic decrease of concentration of isolated europium dipoles induced by LNT irradiation. Moreover, the relationship between F center and Eu(2+) dipoles is different than that predicted by the theory {divides}8{divides}. The results obtained are explained by radiation induced aggregation of Eu(2+) dipoles into small clusters at LNT.
