XANES and micro-Raman spectroscopy study of the barium titanosilicates BaTiSi2O7 and BaTiSi4O11

Popis výsledku v původním jazyce

The coordination environment around Ti4? in the photoluminescent compound BaTiSi2O7 and in BaTiSi4O11 was investigated with X-ray absorption nearedge structure spectroscopy and micro-Raman spectroscopy. The presence of VTi in TiO5 pyramidal units with one short Ti–O bond involving the apical oxygen was detected in both compounds. Interpretation of the vibrational signal from the silicate framework suggested that BaTiSi4O11 is a metasilicate containing building units ofnSiO4 tetrahedra, which are larger than in other barium titanosilicates. These results confirmed the same structural environment of Ti4? as recently disclosed by structure refinement of BaTiSi2O7 and provided new insights into the unknown structure of BaTiSi4O11 in the light of the study of its physical properties as potential functional material.
