摘要通过溶胶-凝胶法制备了具有白光发射的Gd₄Ga₂O₉: x%Dy³⁺荧光粉,利用 X 射线粉末衍射( XRD)、扫描电子显微镜(SEM)、能谱仪(EDS)、紫外-可见漫反射光谱(UV-Vis DRS)和荧光光谱等对产物的物相结构、形貌、组分和光学性能进行研究,并分析了Dy³⁺掺杂量对样品的影响。XRD结果表明,所制备的样品为Dy³⁺掺杂的Gd₄Ga₂O₉单斜晶体和少量Ga₂O₃杂质相的混合物。紫外-可见漫反射光谱结果表明制备的Dy³⁺掺杂Gd₄Ga₂O₉晶体是一种光学带隙为5.29 eV的直接带隙半导体。荧光检测结果表明Dy³⁺掺杂Gd₄Ga₂O₉荧光粉可被属于Gd³⁺激发带的275 nm紫外光有效激发,并在490 nm和575 nm附近分别发射出属于Dy³⁺的⁴F_9/2→⁶H_15/2和⁴F_9/2→⁶H_13/2跃迁的蓝色和黄色的强烈光,证实在Gd₄Ga₂O₉: Dy³⁺样品中存在显著的由Gd³⁺到Dy³⁺的能量传递发光现象。同时,对其发光机制进行了讨论。样品的发光强度随着Dy³⁺掺杂量的变化而变化,同时影响着样品的发光颜色,Dy³⁺掺杂量为1.5% 和2% 时制备的荧光粉可在紫外光激发下分别发射出CIE色坐标为(0.336 2,0.351 2)和(0.338 1,0.352 3)、相关色温为5 340 K和5 263 K的白色光。研究结果表明Gd₄Ga₂O₉: Dy³⁺是一种潜在的紫外光激发白光发射荧光材料。

Abstract: Gd₄Ga₂O₉: x%Dy³⁺ phosphors with white light emission were prepared by sol-gel method. The phase structure, morphology, composition and optical properties of the samples were studied by X-ray powder diffraction (XRD), scanning electron microscope (SEM), energy dispersive X-ray spectrometry (EDS), UV-Vis diffuse reflectance spectroscopy (UV-Vis DRS), and photoluminescence spectroscopy (PL). The XRD results show that the samples are mixtures of Dy³⁺ doped Gd₄Ga₂O₉ monoclinic crystals and a slight impurity phase corresponding to Ga₂O₃. The results of UV-Vis DRS indicate that the Dy³⁺ doped Gd₄Ga₂O₉ crystal is a direct semiconductor with an optical band gap of 5.29 eV. The PL results reveal that the Dy³⁺ doped Gd₄Ga₂O₉ phosphors can be effectively excited by an excitation band of Gd³⁺ at 275 nm, and emit intense blue and yellow light at 490 nm and 575 nm, which attribute to the ⁴F_9/2→⁶H_15/2 and ⁴F_9/2→⁶H_13/2 transitions of Dy³⁺, respectively, confirming that there is an obvious energy transfer luminescence phenomenon from Gd³⁺ to Dy³⁺ in Gd₄Ga₂O₉: Dy³⁺ samples. The possible luminescence mechanism of Gd₄Ga₂O₉: Dy³⁺ phosphors was briefly proposed. The luminous intensity of the sample varies with the doping amount of Dy³⁺, which also affects the luminous color of the prepared product. The Gd₄Ga₂O₉: 1.5%Dy³⁺ and Gd₄Ga₂O₉: 2.0%Dy³⁺ phosphors can emit white light with CIE color coordinates of (0.336 2, 0.351 2) and (0.338 1, 0.352 3) and correlated color temperatures of 5 340 K and 5 263 K under the excitation of ultraviolet light, respectively. The results imply that Gd₄Ga₂O₉: Dy³⁺ is a potential white light emitting luminescence mate-rial excited by ultraviolet light.

Key words: Gd₄Ga₂O₉ Dy³⁺ doped white light emitting luminescence property energy transfer direct semiconductor
