Abstract
The fluorescence of the Cu+ impurity centre in KBr was investigated in the range 19-300 K; in particular, lifetime and quantum yield data we re recorded in the same sets of measurements. The de-excitation mechan ism is interpreted in terms of the Pedrini model: two excited states i n thermal equilibrium are involved in the emission process, one of whi ch is metastable and lies close below the emitting level.
