The relative spectral distribution of the fluorescence of both untreated and radiation-colored LiF crystals were investigated at monochromatic excitation in the range from 253 to 635 nm. Fluorescence was shown to be slightly influenced by the growing procedure of the crystals (air or vacuum-grown) and the type of coloration (x rays or deuterons), but it was not until longer exciting wavelengths were used that this influence became more distinct. Fluorescences with peaks at 530 and 870 nm emitted at R₁, R₂, or M ban excitation could be verified. In addition, at F band excitation an emission was observed likewise at 530 and 670 nm, which could also be stimulated, individually or commonly, by light of the R₁, R₂, or M bands. This may be interpreted in terms of an energy transfer process from the absorbing to the emitting centers.
