摘要

摘要采用原位粉末 X 射线衍射法研究了硼酸 SrBi2B2O7 在 -175 至 25°C 温度范围内的热膨胀。计算了 Sr1 - xBaxBi2B2O7 固溶体的成分变形。通过吸收光谱测定了固溶体的带隙。确定了热变形和成分变形的相似性。这些变形与 Sr1 - xBaxBi2B2O7 固溶体的晶体结构进行了比较。

Compositional Deformations, Absorption Spectroscopy, and Low-Temperature X-Ray Diffraction of Sr1 – xBaxBi2B2O7 Solid Solutions

Thermal expansion of SrBi₂B₂O₇ borate was investigated by in situ powder X-ray diffraction in the temperature range from –175 to 25°C. Compositional deformations of Sr_1 – xBa_xBi₂B₂O₇ solid solutions were calculated. The band gaps for solid solutions were determined by the absorption spectroscopy. A similarity of thermal and compositional deformations has been established. These deformations were compared with the crystal structure of Sr_1 – xBa_xBi₂B₂O₇ solid solutions.
