| description | Rare earth oxysulfides possess excellent energy transfer efficiency, along with remarkable thermal and chemical stabilities. Currently, it remains a challenging research focus to fluorescent powder characterized by a small particle size, narrow distribution, and high luminescence intensity. Here, we primarily investigate ways to enhance the luminescent intensity of rare earth sulfur oxide phosphors synthesized via the sulfur fusion method and to reduce the particle size of these phosphors. By using the sulfur melting technique, fluorescent powder was created, with doping ions Tb3+ and La3+ of rare earth integrated. Various methods such as fluorescence spectroscopy, and X-ray diffraction were employed to investigate how rare earth terbium and lanthanum doping impacts the lattice structure and luminescent capabilities of gadolinium oxysulfide. The experimental results indicate that the fluorescent powder has a pure hexagonal crystal structure. The luminescence intensity of the fluorescent powder reaches its maximum when the doping concentration of Tb3+ is 2mol%. When the La3+ doping concentration is 60mol%, the luminescence intensity is 1.9 times that of the undoped La3+ sample. Therefore, introducing rare earth terbium and lanthanum atoms can effectively improve the optical properties of fluorescent powders.
