    The paper presents absorption, emission and decay kinetics of the series of crystals KBr:In+, KBr:Pb2+ and KBr:Bi3+. 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:Pb2+ has known non-exponential shape the decays of KBr:In+ and KBr:Bi3+ main emissions are single exponential. The decay of KBr:In+ emission at 422 nm consist only one component with lifetime equal 16.2 ls at 8 K. The decay of KBr:Bi3+ emission at 392 nm has evidently two component, fast and slow ones, and lifetime corresponding to slow one is 2.1 ms.
