Conference paper


A weak infrared luminescence (1.8–3.5 µm) has been observed from UV excited OH- impurity ions in KBr crystals. The luminescence signal disappears at temperatures above ~ 100 K. The analysis of the results and the correlation with the temperature dependence of the emission from the electronic transition indicates that the IR emission is due to the decay of the vibrational stretching mode of the ground electronic state.
