Abstract

The rapid decay of the excited state of the F centers in KBr:OH- has been measured by mean of a pump and probe technique with picosecond time resolution. The lifetime of the F centers (τ ~ 1 μs at 77 K) is shortened in the OH- doped samples, to τ ∼ 310 ps. The quenching of the normal radiative lifetime seems to be related to librational excitation of the OH- molecular ion. © 1993.
