智利Catolica del Norte大学理学系S.Fuentes等人将溶胶-凝胶法同水热法结合起来,在60psi氧分压下合成了掺杂Eu的BaTiO3相,用X-射线粉末衍射法表微晶体相结构,对Raman谱和磁性也进行了研究。荧光发射光谱证明,近紫外光可以有效地激发试样。由于电双极转变5 D0→7F2的红辐射能带成为整个谱线的最主要部分。对Raman谱线、光特性及磁性三者
S.Fuentes et al., Department of Science, Catolica del Norte University, Chile, combined the sol-gel method with the hydrothermal method to synthesize the Eu-doped BaTiO3 phase at a partial pressure of oxygen of 60 psi and X-ray powder diffraction The bulk structure, Raman spectra and magnetic properties were also studied. Fluorescence emission spectroscopy proved that near-ultraviolet light can effectively stimulate the sample. Due to the electric dipole transition 5 D0 → 7F2 red radiant energy band becomes the most important part of the entire spectrum. Raman line, optical properties and magnetic three
