摘要
FT-Raman spectra of some calcium phosphates, calcium carbonate and calcium hydroxide are reported. Comparing with dispersive Raman spectra, it is shown that some strong bands in the FT-Raman spectra of these compounds which have been erroneously assigned to Raman bands, are in fact fluorescence emission bands. The origin of these fluorescence bands have been discussed in terms of rare earth impurities in a particular structure. It is further concluded that in using FT-Raman spectroscopy of minerals, care should be taken in not confusing the fluorescence bands with Raman scattering bands. (C) 1997 Elsevier Science B.V.
