摘要：
Radiative characteristics of localized exciton states in a KCl:I crystal have been studied in the temperature range 27–200 K by pulsed optical spectroscopy with nanosecond-range time resolution. Besides the bands investigated earlier in KCl:I crystals at impurity concentrations above 0.1 mol %, a strong band peaked at 3.8 eV was detected. The temperature dependences of the decay times, amplitude values of the intensity, and light sums of the 3.8-and 3.4-eV bands were studied. These bands are shown to originate from radiative decay of localized excitons bound to the impurity dimers.
