Abstract—

We have prepared ErF₃-doped glasses in the ZrF₄–BaF₂–LaF₃–AlF₃–NaF system containing chlorine ions substituted for fluorine ions. The crystallization behavior of the chlorine-substituted glasses has been studied at various BaCl₂ and ErF₃ concentrations. We have identified phases precipitating during heat treatment of the glasses and assessed the effect of chlorine substitution for fluoride on the optical absorption and IR luminescence in the glasses. The results demonstrate that chlorine substitution for fluorine causes the UV absorption edge of the glass to shift to longer wavelengths and produces an additional absorption in the visible spectral region. The formation of crystalline phases during heat treatment of the glasses leads to significant changes in the shape of the Er³⁺ luminescence bands at 0.98 and 1.55 μm.

掺lor氯代氟锆酸盐玻璃的结晶行为和光谱性质

摘要-

我们已经在ZrF ₄ -BaF ₂ -LaF ₃ -AlF ₃ -NaF系统中制备了掺ErF _3的玻璃，其中含有氯离子代替氟离子。已研究了在各种BaCl ₂和ErF _3下氯取代玻璃的结晶行为浓度。我们已经确定了在玻璃热处理过程中析出的相，并评估了氯替代氟化物对玻璃的光吸收和IR发光的影响。结果表明，氯取代氟会导致玻璃的紫外线吸收边缘移至更长的波长，并在可见光谱区域产生额外的吸收。在玻璃的热处理期间结晶相的形成导致在0.98和1.55μm处的Er ³⁺发光带的形状发生显着变化。
