We manufactured a new series of borosilicate glass doped with Dy3+ ions using a glass-quenching technique. To achieve the unique luminescence properties of our prepared glass, rare earth (Dy2O3) was incorporated into the glass matrix. The photoluminescence spectrum revealed five intense emission bands allocated at wavelengths 483 nm, 575 nm, 665 nm, 712 nm, and 752 nm, attributed to the transition from 4F9/26H15/2, 4F9/26H13/2, 4F9/26H11/2, 4F9/26F3/2, and 4F9/26H9/2 respectively. From the emission results of prepared glass at excitation wavelength 350 nm, we used our glass as a new solid laser source for the production of white light. From radiative properties measurements, the luminescence performance of fabricated samples showed a strong transition, with limited transition life and high values of branching ratio. Additional physical parameters were evaluated, such as density, optical packing density, and molar volume. By X-ray diffraction, we observed that all the prepared samples were of the amorphous phase. Fourier Transform Infrared Spectroscopy demonstrated the effect of incorporating Dy2O3 on the structure of our prepared glass. From the spectrum of absorption transitions, optical band gap Eg, refractive index (n), and Urbach energy (ΔE) were obtained. To research glass bonding nature, Judd-Ofelt strength parameters (Ωλ and λ = 2, 4, 6) were obtained; these parameters were used to achieve the spectroscopic efficiency factor, branching ratios (βr), and lifetime (τ). Moreover, the cross-sections of emission and absorption of our prepared glass was estimated. Finally, our cumulative study findings indicate that these manufactured samples may be used in luminescent display devices as a white light laser diode (W-LED).

Dy 2 O 3掺杂硼硅玻璃的结构和发光特性研究

我们使用玻璃淬火技术制造了一系列掺杂 Dy 3+离子的新系列硼硅酸盐玻璃。为了实现我们制备的玻璃的独特发光特性,将稀土 (Dy 2 O 3 ) 加入到玻璃基质中。光致发光光谱显示五个强发射带分布在波长 483 nm、575 nm、665 nm、712 nm 和 752 nm,归因于从4 F 9/26 H 15/24 F 9/26 H 13/2 , 4 F 9/26 H 11/2 ,4 F 9/26 F 3/24 F 9/26 H 9/2分别。根据制备的玻璃在激发波长 350 nm 下的发射结果,我们将我们的玻璃用作产生白光的新型固体激光源。从辐射特性测量来看,制造的样品的发光性能表现出强烈的转变,转变寿命有限,支化比值高。评估了其他物理参数,例如密度、光学堆积密度和摩尔体积。通过 X 射线衍射,我们观察到所有制备的样品都是非晶相。傅里叶变换红外光谱证明了加入 Dy 2 O 3对我们制备的玻璃结构的影响。从吸收跃迁光谱,光学带隙E g,获得了折射率 ( n ) 和 Urbach 能量 ( ΔE )。为研究玻璃粘合性质,获得了 Judd-Ofelt 强度参数(Ω λλ  = 2, 4, 6);这些参数用于获得光谱效率因子、分支比 ( βr ) 和寿命 ( τ )。此外,估计了我们制备的玻璃的发射和吸收截面。最后,我们的累积研究结果表明,这些制造的样品可作为白光激光二极管 (W-LED) 用于发光显示设备。
