Sažetak
Strong anti-Stokes bands observed in FT-Raman spectra of Y2O3, La2O3, Gd2O3 and Lu2O3 are explained by NIR luminescence of Yb3+ impurities present in sesquioxides after the excitation with the 1064 nm line of a Nd:YAG laser. Samples of Y2O3:Yb, La2O3:Yb, Ga2O3:Yb, CeO2:Yb, Gd2O3:Yb and Lu2O3:Yb were prepared by solution combustion synthesis procedure using urea. All materials were investigated by FT-Raman and FT-NIR spectroscopy and characterized by X-ray powder diffraction. Strong anti-Stokes luminescence caused by Yb3+ ions in FT-Raman spectra has a potential application of qualitative and quantitative determination of ytterbium in solid materials.
