Abstract

This study examined magnesium borotellurite glass systems added with neodymium oxide and titanium especially the elastic, structural, and physical properties. A sequence of neodymium and titanium added magnesium borotellurite glass was produced and expressed using a formula that displays the proportion of each component as following (56-\(\:y\))TeO₂–30B₂O₃–10MgO–4Nd₂O₃–yTiO₂, with y = 0, 1, 2, 3, and 4 mol%. The density of the Ti-added MBTNd glass was decreased from 4.16 g/cm³ to 4.14 g/cm³ by adding titanium. Besides, molar volume decreased from 30.54 cm³/mol to 29.92 cm³/mol. XRD analysis prove the amorphous state of glasses. The Urbach energy has decreases because of the titanium ion implantation with the highest value of 0.339 eV for the MBTNdTi-4 glass sample. The indirect and direct band gap energies showed a downward trend with increasing TiO₂ content, attaining their minimum values at 2.498 eV for the MBTNdTi-4 glass (indirect transition) and 3.324 eV for the MBTNdTi-3 glass (direct transition). The MBTNdTi-2 glass sample exhibited the strongest PL emission, indicating that this composition provides the optimal TiO₂ concentration for maximizing luminescence efficiency.

TiO2对56TeO2-30B2O3-10MgO-4Nd2O3玻璃体系结构和光学性能的影响

本研究考察了添加氧化钕和钛的镁硼碲酸盐玻璃体系，特别是弹性、结构和物理性能。制备了一系列添加了钕和钛的硼碲酸镁玻璃，并使用公式表示了各组分的比例为（56- \(\:y\)） TeO2-30B2O3-10MgO-4Nd2O3-yTiO2, y = 0,1,2,3和4mol%. The density of the Ti-added MBTNd glass was decreased from 4.16 g/cm3 to 4.14 g/cm3 by adding titanium. Besides, molar volume decreased from 30.54 cm3/mol to 29.92 cm3/mol. XRD analysis prove the amorphous state of glasses. The Urbach energy has decreases because of the titanium ion implantation with the highest value of 0.339 eV for the MBTNdTi-4 glass sample. The indirect and direct band gap energies showed a downward trend with increasing TiO₂ content, attaining their minimum values at 2.498 eV for the MBTNdTi-4 glass (indirect transition) and 3.324 eV for the MBTNdTi-3 glass (direct transition). The MBTNdTi-2 glass sample exhibited the strongest PL emission, indicating that this composition provides the optimal TiO₂ concentration for maximizing luminescence efficiency.
