Abstract

Oxyfluoride glasses in the CaF₂–SiO₂–B₂O₃–Bi₂O₃–Y₂O₃–ZnO system have been designed and prepared at various ratios of batch components, and we have studied absorption spectra and luminescence properties of Eu₂O₃-doped glasses. According to X-ray diffraction data, all of the glasses are X-ray amorphous. We have determined their glass transition temperature (t_g). Their local structure has been studied by IR spectroscopy and it has been shown that, independent of composition, the glasses contain complex polyborate anions formed by [BO₃] and [BO₄] groups. Bismuth is incorporated into the glass network to form Bi–O–Si bonds and [BiO₆] network-former groups.

Eu 2 O 3掺杂氟氧化物玻璃的制备，吸收光谱和发光性能

摘要

在CaF ₂ -SiO ₂ -B ₂ O ₃ -Bi ₂ O ₃ -Y ₂ O ₃ -ZnO体系中设计和制备了不同比例配合物的氟氧化物玻璃，并研究了Eu的吸收光谱和发光特性₂ O ₃掺杂的玻璃。根据X射线衍射数据，所有的眼镜都是X射线无定形的。我们确定了它们的玻璃化转变温度（t _g）。通过红外光谱研究了它们的局部结构，结果表明，玻璃与成分无关，含有由[BO]形成的复杂的多硼酸根阴离子。₃ ]和[BO ₄ ]组。铋被掺入玻璃网络中以形成Bi–O–Si键和[BiO ₆ ]网络形成者基团。
