“…FT-Raman has wide applications and several good reviews detailing the application of this technique to a diverse range of fields are available (Brody et al, 1999a,b;Lewis and Edwards, 2001), including FT-Raman use in soil chemistry (Bertsch and Hunter, 1998;Hayes and Malcolm, 2001;Kizewski et al, 2011). This technique has been adapted to obtain quality data from the soil components: humic and fulvic acids (Yang and Wang, 1997) and clay minerals (Aminzadeh, 1997;Coleyshaw et al, 1994;Frost et al, 2010b;Frost and Palmer, 2011;Frost et al, 1997). However, few studies on more complex samples such as whole soils have been performed (Francioso et al, 1996).…”

“…Additionally, it was mentioned that the locality and chemical environment is very important in the luminescence of a particular mineral. Ten years ago, Aminzadeh 16 confirmed that the same mineral type (calcium triphosphate), depending on the locality of its origin, in some cases, show identical conventional Raman and FT-Raman spectra, whereas in other cases, unexpected bands might additionally appear in the FT-Raman spectra that are absent in the conventional Raman spectrum.…”

Two strong bands centered at 446 and 607 cm −1 have been observed in the FT-Raman spectrum of almandine [Fe 3 Al 2 (SiO 4 ) 3 ] excited with 1064 nm, which were completely absent in the corresponding dispersive Raman spectra obtained using 488, 514.5 and 532 nm excitation. Furthermore, the mentioned strong bands have not been registered in the anti-Stokes side of the FT-Raman spectrum, and were therefore assigned to laser-induced fluorescence bands. Their appearance is related to the presence of rare-earth element traces as impurities in the almandine sample. Additionally, the FT-Raman (and dispersive Raman) spectrum of the isomorphous spessartine [Mn 3 Al 2 (SiO 4 ) 3 ] mineral has been introduced, which did not show the presence of these fluorescence emission bands. The purity of the minerals was confirmed by study of their powder X-ray diffraction (PXRD) patterns.

“…The LIF spectrum of lime paste ( Fig. 2b) consist on a broad band ranging from 300 to 650 nm with some overimposed structure with local maxima at 370, 400 and 430 nm [26]. These fluorescent emissions can be assigned to the organic residues of lime paste, fabricated, according to the manufacturer (see Experimental section), by mixing calcinated limestone, water and some animal fat.…”
