| description | The invention discloses a borophosphate near-infrared two-region fluorescent material as well as a preparation method and application thereof. The chemical composition of the fluorescent material is Ba3BP1-xO7: xMn < 5 + >, Mn < 5 + > is an activating agent, and x is 0.001-0.03. The preparation method is a high-temperature solid-phase method and comprises the following steps: weighing a Ba source, a B source, a P source and a Mn source according to a stoichiometric ratio, uniformly mixing the raw materials, sintering at high temperature in an air atmosphere, naturally cooling to room temperature to obtain a sintered product, and grinding the sintered product to obtain the borophosphate near-infrared two-region fluorescent material. The fluorescent material provided by the invention can be effectively excited by a commercial red light LED chip, and forms narrow-band emission in a near-infrared second region. The borophosphate near-infrared two-region fluorescent material has good physical and chemical stabilit |
