摘要

The paper presents absorption, emission and decay kinetics of the series of crystals KBr:In~+, KBr:Pb~(2+) and KBr:Bi~(3+). All these ions have similar electronic structure of the lowest excited state which is shaped mainly by dynamic Jahn-Teller effect. While the slow decay curve of KBr:Pb~(2+) has known non-exponential shape the decays of KBnln~+ and KBr:Bi~(3+) main emissions are single exponential. The decay of KBr:In~+ emission at 422 nm consist only one component with lifetime equal 16.2 μs at 8 K. The decay of KBnBi~(3+) emission at 392 nm has evidently two component, fast and slow ones, and lifetime corresponding to slow one is 2.1 ms.
