Abstract The Dy3+ ions doped tungsten gadolinium borate (Dy-WGdB) glasses were synthesis by the melt-quenching technique with various Dy2O3 concentrations. The physics, optical and several types of luminescence properties in the Dy-WGdB glass samples were researched. Glass densities (~6.0 g/cm3) indicates that the compaction of glass is high and rise with an increment of Dy2O3 concentrations. The Dy-WGdB glass samples absorb photons in visible light (VIS) and near-infrared (NIR) region from the absorption spectra. For photo-, radio- and proton luminescence, the highest emission was observed at 575 nm, corresponding to Dy3+ transition 4F9/2 → 6H13/2. The maximum concentration of Dy2O3 doped in the WGdB glass is 1.0 mol%, which has achieved the highest emission intensity in all three types of luminescence. For 1.0 mol% doped glass, the decay times under pulse X-ray excitation was measured and found to be 0.216 ms. The temperature dependent luminescence spectra of the 1.0% doped glass in a temperature range, 10 K–300 K was measured and found the thermal quenching. In this research, under the photo, X-ray and proton excitation, the WGdB glass doped with Dy2O3 displays the strong luminescence in the VIS region. It has the potential for applications in high-energy and nuclear physics, radiation control and homeland security.

开发用于光子学和闪烁材料应用的掺杂 Dy3+ 的 WO3-Gd2O3˗ B2O3 高密度玻璃

摘要 Dy3+ 离子掺杂的硼酸钨钆 (Dy-WGdB) 玻璃是通过熔体淬火技术在不同 Dy2O3 浓度下合成的。研究了 Dy-WGdB 玻璃样品的物理、光学和几种类型的发光特性。玻璃密度 (~6.0 g/cm3) 表明玻璃的压实度很高,并且随着 Dy2O3 浓度的增加而增加。Dy-WGdB 玻璃样品从吸收光谱中吸收可见光 (VIS) 和近红外 (NIR) 区域的光子。对于光、射电和质子发光,在 575 nm 处观察到最高发射,对应于 Dy3+ 跃迁 4F9/2 → 6H13/2。WGdB 玻璃中掺杂的 Dy2O3 的最大浓度为 1.0 mol%,在所有三种类型的发光中都达到了最高的发射强度。对于 1.0 mol% 掺杂玻璃,测量了脉冲 X 射线激发下的衰减时间,发现为 0.216 ms。在温度范围 10 K–300 K 内测量了 1.0% 掺杂玻璃的温度相关发光光谱并发现了热猝灭。本研究中,在照片、X射线和质子激发下,掺有Dy2O3的WGdB玻璃在可见光区显示出强烈的发光。它具有在高能和核物理、辐射控制和国土安全方面的应用潜力。掺有 Dy2O3 的 WGdB 玻璃在可见光区显示出强烈的发光。它具有在高能和核物理、辐射控制和国土安全方面的应用潜力。掺有 Dy2O3 的 WGdB 玻璃在可见光区显示出强烈的发光。它具有在高能和核物理、辐射控制和国土安全方面的应用潜力。
