Polarized luminescence of (Ga + ) 2 , (In + ) 2 and (Tl + ) 2 centres in KCl crystals is investigated experimentally. In the series of KCl, KBr, and KI crystals the (Tl + ) 2 centres are studied in order to clear up the influence of the anions on the (A + ) 2 centre properties. The quasimolecules [Tl 2 X 10 ] 8‐ and [T1 2 X 11 ] 9‐ , where X are Cl − or I − ions, with the symmetry D 2h and D 4h , respectively, were theoretically considered by a MO method. An attempt is made to prove the model of the (A + ) 2 centres basing on a comparison of the results of the experimental and theoretical investigations.
