Abstract

Thulium/holmium co-doped bismuth borotellurite glass have been prepared using melt quenching technique. All the prepared glasses characterized using X-ray Diffraction (XRD) and Fourier-transform infrared (FTIR) spectroscopy at room temperature. There is no distinct peak in the XRD patterns over the observed range of 10° to 90°, indicating that all prepared glasses are amorphous. FTIR study reveals that the glass structure is composed of by TeO₃, TeO₄, BO₄, BO₃, BiO₃, and BiO₆ structural units. According to the bridging and non-bridging oxygen, the impact of the Ho₂O₃ addition was demonstrated by the calculated ratio of BO₄ to TeO₄ in the structural network. Bridging oxygen formation was proposed by the calculated ratio of BO₄ to TeO₄ increasing in along with the increase in Ho₂O₃ concentration (x = 0 to 1.0 mol %). Additionally, the declining ratio of BO₄ to TeO₄ (x = 1.5 to 2.5 mol %) explains the formation of non-bridging oxygen.

用FTIR分析Tm2O3/Ho2O3共掺硼碲酸盐玻璃的结构性能

采用熔融淬火技术制备了铥/钬共掺硼碲酸铋玻璃。用x射线衍射（XRD）和傅里叶变换红外光谱（FTIR）在室温下对所制备的玻璃进行了表征。在观察到的10°~ 90°范围内，XRD谱图没有明显的峰，表明所制备的玻璃均为非晶态。FTIR研究表明，该玻璃结构由TeO3、TeO4、BO4、BO3、BiO3和BiO6结构单元组成。根据架桥氧和非架桥氧，通过计算结构网络中BO4与TeO4的比例来证明Ho2O3的加入对结构网络的影响。通过计算BO4与TeO4的比值随着Ho2O3浓度的增加（x = 0 ~ 1.0 mol %）而增加，提出了桥式氧生成。此外，BO4与TeO4的比值下降（x = 1.5 ~ 2.5 mol %）解释了非桥氧的形成。
