| Resumo : | The influence of the presence of barium carbonate (BaCO3) phase on the luminescence properties of barium titanate nanocrystals (BaTiO3) powders was investigated. Structural and optical characterizations of erbium (Er3+) doped BaTiO3 synthesized by thesol-emulsion-gel were performed. Using Fourier transform infrared spectroscopy and X-ray powder diffraction, we identified thepresence of impurities related to BaCO3 and quantified its fraction. It was observed that the presence of BaCO3 phase, even at lowlevels, depletes significantly the infrared-to-visible upconverted luminescence efficiency of the produced nanopowders. |
