Abstract Dysprosium (Dy3+)-doped antimony-magnesium-strontium-oxyfluoroborate (B2O3 MgF2 SrO Sb2O3 Dy2O3, BMFSrSbD), glasses were synthesized by traditional melt-quenching method. The synthesized samples have been analyzed by X-ray diffraction, optical absorption and fluorescence techniques for deriving various characteristic properties. Emission spectra of Dy3+: samples were exhibit three well resolved emission bands at around 482, 575 and 666 nm which originated from the 4F9/2→6H15/2, 4F9/2→6H13/2 and 4F9/2→6H11/2 transitions upon excitation of wavelength at 452 nm. Decay curves of the 4F9/2 level of Dy3+ ion were display mono-exponential at low Dy3+ concentration (0.1 mol%) and deviated to non-exponential behavior at high concentration of Dy3+ ions (≥ 0.5 mol%). Lifetime of the 4F9/2 level was decreased with increase of Dy3+ ions concentration. Chromaticity coordinates (x,y) of Dy3+:BMFSrSbD samples were evaluated and represented in CIE 1931 chromaticity diagram, appear in the whitish-yellow region. The results suggest that these glasses could be utilized as a potential candidate for the development of display devices and lasers at a wavelength of 575 nm.

镝掺杂锑镁锶氧氟硼酸盐玻璃的结构和光致发光

摘要 镝 (Dy3+) 掺杂的锑镁锶氧氟硼酸盐 (B2O3 MgF2 SrO Sb2O3 Dy2O3, BMFSrSbD) 玻璃采用传统的熔体淬火方法合成。合成的样品已通过 X 射线衍射、光吸收和荧光技术进行分析，以获得各种特性。Dy3+ 的发射光谱：样品在 482、575 和 666 nm 附近表现出三个解析良好的发射带，它们源自 4F9/2→6H15/2、4F9/2→6H13/2 和 4F9/2→6H11/2 跃迁激发波长为 452 nm。Dy3+ 离子的 4F9/2 能级的衰减曲线在低 Dy3+ 浓度（0.1 mol%）时显示为单指数，而在高 Dy3+ 离子浓度（≥ 0.5 mol%）时偏离非指数行为。4F9/2 能级的寿命随着 Dy3+ 离子浓度的增加而减少。Dy3+:BMFSrSbD 样品的色度坐标 (x,y) 被评估并在 CIE 1931 色度图中表示，出现在黄白色区域。结果表明，这些玻璃可以用作开发显示设备和波长为 575 nm 的激光器的潜在候选材料。
