摘要
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.
Role of TiO2 to the structural and optical properties of 56TeO2–30B2O3–10MgO–4Nd2O3 glass system
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.
