In recent years, much research effort has been directed towards the synthesis of rare-earth (RE3+) doped functional materials since they can be used as highly efficient phosphors, catalysts, and optics materials by virtue of their unique optical, electronic, and chemical properties , ,  and . For applications involving NUV excitation (300–400 nm) for the generation of a variety of display panels, Tb3+ ion is a well-known activator that effectively emits green light in diverse host lattices. However, the intensities of the Tb3+ Volasertib peaks in the NUV region are very weak and their widths are very narrow due to the strictly forbidden 4f–4f transitions. This severely limits its performance under NUV excitation  and . One of the strategies to solve the above problem is using Ce3+ as a sensitizer because it has a strong excitation band originating from allowed 4f–5d transitions, which could efficiently absorb the NUV light and transfer the excitation energy to Tb3+, then result in strong sensitized green emission . With this strategy, green phosphors with good luminescent properties, such as Sr2B2O5: Ce3+, Tb3+ , La6Ba4(SiO4)6F2: Ce3+, Tb3+  and BaAl2B2O7: Ce3+,Tb3+  have been synthesized.
