In the present study, hexagonal structured borate phosphors BaLaB9O16 were prepared using a combustion method with colour-tunable emission properties achieved by varying the doping concentration of Eu3+ and Tb3+ in the cluster. The as-prepared materials were analyzed for structural and morphological parameters through X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM) studies. Tuning of colour was predicted through the photoluminescence and photoluminescence excitation spectra of the materials that showed good green and red emissions when doped with Tb3+ and Eu3+, respectively, whereas the emission of the co-doped sample (Eu3+ and Tb3+) can be varied from the green region to red region by varying the excitation range from 207 to 254 nm.

颜色可调 Eu3+/Tb3+ 共掺杂 BaLaB9O16 的微波辅助燃烧合成及发光特性
在本研究中，六方结构的硼酸盐荧光粉 BaLaB 9 O 16是使用燃烧方法制备的，其具有通过改变簇中 Eu 3+和 Tb 3+的掺杂浓度实现的颜色可调发射特性。通过 X 射线衍射 (XRD) 和场发射扫描电子显微镜 (FE-SEM) 研究分析了所制备材料的结构和形态参数。通过分别掺杂 Tb 3+和 Eu 3+时显示出良好绿色和红色发射的材料的光致发光和光致发光激发光谱预测颜色的调整，而共掺杂样品（Eu 3+和 Tb 3+ ) 可以通过从 207 到 254 nm 改变激发范围而从绿色区域变化到红色区域。
