| titleOfInvention | A kind of blue is to the adjustable silicate fluorescent powder of green color and preparation method thereof |
| abstract | The present invention discloses a kind of blue to the adjustable silicate fluorescent powder of green color and preparation method thereof.The chemical composition expression of the fluorescent powder are as follows: NaBa 3 La 3(1‑x‑y) Ce 3x Tb 3y Si 6 O 20 ；Wherein, x, y are ion Ce respectively 3+ And Tb 3+ Opposite La 3+ The molar percentage coefficient accounted for, 0.001≤x≤0.01,0.05≤y≤0.40.The fluorescent powder is rhombic system, space group Ama2.The fluorescent powder is under the ultraviolet excitation of 310-385nm, and emission peak is between 345-630nm, by regulating and controlling Ce 3+ And Tb 3+ Doping ratio, can effectively adjust the ratio of black light and bluish-green light emitting peak, and then realize that phosphor material powder is adjustable from blue light to green emission.The preparation method of the fluorescent powder has the advantages that raw material is easy to get, is simple process, at low cost. |
