In the present work, we report the synthesis of Eu doped BaMgAlO nanophosphors, which can be used as red phosphors for display panels and lightning devices. Eu doped BaMgAlO:Eu (=0.0, 0.1, 0.2, 0.4, 0.5, and 0.6) nanophosphors were synthesized by chemical route by varying Eu concentration. Structural/morphological information of prepared nanophosphors and the oxidation state of the doped Eu ions were elucidated by X-ray diffraction/scanning electron microscopy and X-ray absorption near edge spectroscopy, respectively. The optical properties of prepared nanophosphors were studied using the ionoluminescence (IL) technique by bombarding 120 MeV Ag and 100 MeV Ni ions. Ionoluminescence studied by Ag ions shows two different behaviors against applied ion fluences. IL intensity increases initially, followed by a reduction, or it starts decreasing and reaches a minimum value. Also, the ion fluence required to achieve maximum/minimum luminescence is shifted to a lower value with doping percentages. On the other hand, Ni ions irradiation shows an increase in the luminescence followed by reduction/saturation in the intensity for higher ion fluences.

不同掺杂浓度下铕掺杂BaMgAl10O17纳米荧光粉的离子发光

在目前的工作中，我们报道了Eu掺杂BaMgAlO纳米荧光粉的合成，该纳米荧光粉可用作显示面板和照明设备的红色荧光粉。通过改变Eu浓度的化学途径合成了Eu掺杂的BaMgAlO:Eu (=0.0、0.1、0.2、0.4、0.5和0.6)纳米荧光粉。分别通过X射线衍射/扫描电子显微镜和X射线近边吸收光谱阐明了所制备的纳米磷光体的结构/形态信息和掺杂Eu离子的氧化态。使用离子发光（IL）技术，通过轰击 120 MeV Ag 和 100 MeV Ni 离子，研究了制备的纳米磷光体的光学性质。银离子研究的离子发光显示了针对所施加的离子注量的两种不同行为。 IL 强度最初增加，然后减少，或者开始减少并达到最小值。此外，实现最大/最小发光所需的离子注量随着掺杂百分比而转移到较低值。另一方面，Ni 离子照射显示出发光增加，随后强度降低/饱和，以获得更高的离子注量。
