【摘要】 <正>在现代谱学领域中,以结构分析为目的研究得最多和应用得最广的手段,或许当屑红外光谱学,有关红外光谱学理论与技术的大量研究论文和专著,几乎都是以化合物分子及晶格的光谱行为作为讨论对象,而用以研究电子能量跃迁的报道并不多见[1]。本工作选择红外透明的十余种含稀土氟化物玻璃体系,使用岛津IR-435型红外分光光度计及日立U-3400型紫外一可见分光度计在室温下测谱,详细研究了这些非晶态物质在L90-25000hm范围内的吸收光谱,透过光谱及其相关的性质。本文仅介绍更多还原

【Abstract】 In this work,we have measured the optical spectra of some fluoride glasses containing rare earth ions by using Shimadzu IR-435 spectrophotometer and Hitachi U-3400 spectrophotometer at room temperature.The absorption and transmission spectra of these glasses at 190-25000 nm have been examined in detail.In this parper,we report only the absorption spectra of four fluoride glasses containing rare earth ion at 900-8400nm,and discuss the electronic spectra,which is of interest and belong to f-f transition,in the IR spectra.The result shows that fundamental structure of the fluoride glasses is a trigonally distorted octahedra.The environment of rare earth ion in the glasses is the same as that of Zr⁴⁺ion.更多还原
