| titleOfInvention | Borate matrix fluorescent powder and preparation method thereof |
| abstract | The invention provides borate substrate fluorescent powder and a preparation method thereof, belonging to the technical field of luminescent materials. The present invention provides borate matrix fluorescent powder, whose chemical composition is KSrB 5 O 9 ]:nEu 3+ And n is 0.01-0.15. The borate substrate fluorescent powder provided by the invention is characterized in that KSr [ B ] 5 O 9 ]K in (1) + 、Sr 2+ With Eu 3+ Radius is similar so that Eu 3+ Easy to dope, and Sr 2+ May itself become Eu 3+ Ionic sensitizer for improving luminous efficiency, and Eu 3+ The host mainly occupies a non-inversion symmetric center lattice position and emits red light, so that the fluorescent powder with high luminous intensity and red color purity is obtained. |
