Abstract The effect of room-temperature annealing for thirty days on the luminescence of lithium fluoride in the temperature range 100–300 K is studied. The results are examined in the light of recent suggestions that there is a close association between the impurities Mg and Ti within a large defect complex and that the exact wavelength of the emission depends on the aggregation state of Mg. Low-temperature luminescence observations do not support the contention of a large defect complex involving Ti and Mg in different states of aggregation.
