Luminescences from KBr/KI single crystals were observed. Two kinds of them were found. The one was attributed to localized I - ions and the other to aggregated I - ions. They suffered Stokes shift and were quenched thermally at room temperature. In cases of large concentration of KI, both emissions coincided with each other, while a new emission appeared which was coincident with that observed in pure KI crystals. And the nature of exciton in alkali halide was discussed.
