Abstract

Luminescence, decay kinetics and polarization properties of single Tl+-based centres in CsX hosts (X = Cl, Dr, I) are described in a wide temperature interval 0.3 - 400 K. It is shown that four emission bands co-existing at the same relaxed excited state surface belong to this centre. At sufficiently high temperatures all the relaxed excited state minima are mutually connected by the thermally stimulated transitions.
