摘要

采用快速熔淬法制备了两组玻璃,分别为玻璃体系 (Eu2O3)x (Na2O)0.1 (B2O3)0.6 (SLS)0.3-x 和 (Eu2O3)0.01 (Na2O)0.1 (B2O3)0.6 (SLS)0.29-y (MgSO4)y (x 和 y = 0、0.005、0.01、0.03 和 0.05 mol%),以检验 MgSO4 的加入对玻璃性能的影响。XRF 分析证实 SLS 玻璃的化学成分为 70.81wt% SiO2。由于镁的密度较低(1.738 g/cm3),而 Eu 的密度为 5.25 g/cm3,因此在 NaSBEu 玻璃中加入 MgSO4 会降低样品的密度。在 NaSBEu 玻璃中加入 MgSO4 会使 NaSBEu0.005 的带隙值从 3.85 eV 提高到 3.90 eV,间接带隙值从 3.22 eV 提高到 3.23 eV。吸收峰产生于三方硼酸键的弛豫,它引起了硼酸盐的不对称振动伸展。这些玻璃样品网络结构的主要依据是不同结构分组中 BO3 和 BO4 单元的排列。红外吸收峰的尖锐度随着 MgSO4 的加入而增加。

Synthesis and Effect of MgSO4 co-doping on the Optical, IR, and Raman Spectroscopic Studies of Eu3+-Doped Alkaline Silica Borate Glasses Produced with SLS Glass as a Silica Source

Two sets of glasses were prepared by rapid melt quench method in the glass system (Eu2O3)x (Na2O)0.1 (B2O3)0.6 (SLS)0.3-x and (Eu2O3)0.01 (Na2O)0.1 (B2O3)0.6 (SLS)0.29-y (MgSO4)y with x and y = 0, 0.005, 0.01, 0.03, and 0.05 mol% to check the effect of MgSO4 inclusion on the glass properties. XRF analysis confirmed the chemical composition of the SLS glass to be 70.81wt% SiO2. The addition of MgSO4 to NaSBEu glasses lowered the sample’s density due to the lower density of Mg (1.738 g/cm3), whereas Eu has a density of 5.25 g/cm3. Adding MgSO4 to NaSBEu glasses raised the band gap values from 3.85 to 3.90 eV and the indirect band gap from 3.22 to 3.23 eV for NaSBEu0.005. The absorption peaks result from the trigonal BO3 bond's relaxation, which causes asymmetric vibrational stretching of the borate. The primary basis for the network structure of these glass samples is the arrangement of BO3 and BO4 units in various structural groupings. The sharpness of the IR absorption peaks increases with the addition of MgSO4.

期刊介绍: The journal Silicon is intended to serve all those involved in studying the role of silicon as an enabling element in materials science. There are no restrictions on disciplinary boundaries provided the focus is on silicon-based materials or adds significantly to the understanding of such materials. Accordingly, such contributions are welcome in the areas of inorganic and organic chemistry, physics, biology, engineering, nanoscience, environmental science, electronics and optoelectronics, and modeling and theory. Relevant silicon-based materials include, but are not limited to, semiconductors, polymers, composites, ceramics, glasses, coatings, resins, composites, small molecules, and thin films.
