Abstract

The laser excited so-called “fluorescence” background from MgO and η-Al2O3 surfaces was studied. Surface hydroxide ions are found to be responsible for this phenomenon, since a clear correlation between background intensity and hydroxyl group density of the surface is observed.

      The coincidence of IR and Raman bands excluded the possibility of there being a centrosymmetric structure in the main digested products. Although the UV–Vis absorption band in the range of 230–260 nm is commonly assigned to the Mo6+=O2- charge transfer (CT) band for tetrahedral coordination, it is also found in spectra of some octahedral coordinated species, such as [Mo7O24]6- and MoO3 (Giordano et al., 1975; Jeziorowski and Knözinger, 1977; Gajardo et al., 1979; Xiong et al., 2000). The two bands at 220 and 310 nm displayed by the spectra of the first few batches of digested solutions can be ascribed to the CT bands for tetrahedral and octahedral coordination respectively without doubt, indicating the coexistence of the octahedral [MoO(OH)(O2)2]2- coordinated species (Howarth et al., 2001) and its hydrolysis products (H2MoO3(O2)).

      In order to reduce this fluorescence, experiments have been carried out in the low wavenumber region. The fluorescence generated by the support can be ascribed to defects and/or to a laser-induced electronic excitation of −OH surface groups [38,39]. The Raman spectrum of the ammonium heptamolybdate is presented in Fig. 2b where the assignment of the different vibrational bands is proposed.

      However, there are discussions of related effects in the literature. Jeziorowski and Knözinger [17] recognized that the fluorescence background in Raman spectroscopy is due to hydroxyl groups on metal oxides, including alumina and magnesium oxide. Rückschloss and coworkers [18] studied the PL of various hydrated metal oxides as a function of annealing temperature, including nanoparticulate alumina and silica, and attributed the blue emission feature at 2.8 eV (440 nm) in the PL spectra to adsorbed hydroxyl groups.
