Witryna1 kwi 1987 · To comprehend the role of impurities optical and thermoluminescent (TL) measurements have been carried out. The effect of impurities on crystal transparency at 420 nm is not correlated with their effect on scintillation. The TL output in the presence of cationic impurities is enhanced while an opposite effect for anionic impurities is … WitrynaAb initio perturbed ion cluster-in-the-lattice calculations of the impurity centers NaI:Tl + and CsI:Tl + are presented. We study several active clusters of increasing complexity and show that the lattice relaxation around the Tl + impurity implies the concerted movement of several shells of neighbors. The results also reveal the importance of …
