| titleOfInvention | Red fluorescent material and preparation method thereof |
| abstract | The invention relates to a novel blue-light-excited red fluorescent material applied to a white light LED (Light Emitting Diode) technology and a preparation method thereof, belonging to the field of light-emitting materials. The blue-light-excited red fluorescent material has a general formula of Bi0.5+dNa0.5-yAy)1-xRxTiO3:fC, wherein R is selected from one or more than one of rare-earth elements Pr, Sm, Eu and Lu, A is selected from one or more than one of the same group of univalent elements K and Li, C is selected from one or more than one of Li, Na, K, Tl and Ag, 0.001<=x<=0.1, 0<=y<=0.5, 0<=d<=0.1, and 0<=f<=0.1. Blue-light-excited red fluorescent powder provided by the invention has good stability, is not easy to deliquesce, does not need cladding treatment, not only has piezoelectric, ferroelectric and dielectric properties, but also has the characteristic of exciting red light by blue light, belongs to a multifunctional photoelectric material, and can be widely applied to fields such as white light LEDs, photoelectricity integration, micro electro mechanical systems, photoelectricity sensors and the like. |
