| description | The invention discloses a method for synthesizing fluorescent powder by adopting a hydrothermal method, the fluorescent powder is Sr0. 79Mg0. 2MoO4: 0.005 Sm < 3 + >, 0.005 Na < + > fluorescent powder, and the doping amount x of Mg < 2 + > is equal to 0.2; the doping amount y of Sm < 3 + > is 0.005; in the synthesis process of the S fluorescent powder, sodium citrate is added as a chelating agent; and PEG20000 (polyethylene glycol 20000) is used as a surface active agent. The Sr0. 79Mg0. 2MoO4: 0.005 Sm < 3 + >, 0.005 Na < + > fluorescent powder prepared by the invention can be excited by 405nm blue light, presents red light emission, and can be used as a red fluorescent material of an LED (Light Emitting Diode).
本发明公开了一种采用水热法合成荧光粉的方法，所述荧光粉为Sr0.79Mg0.2MoO4：0.005Sm3+，0.005Na+荧光粉，Mg2+的掺杂量为x=0.2；Sm3+的掺杂量为y=0.005；在S荧光粉的合成过程中，加入柠檬酸钠作螯合剂；采用PEG20000作为表面活性剂。本发明制备的Sr0.79Mg0.2MoO4：0.005Sm3+，0.005Na+荧光粉可被405nm的蓝光激发，呈现红光发射，可作为LED的红色荧光材料。 |
