| titleOfInvention | Red fluorescent powder excitated by near-ultraviolet broadband and preparation method thereof |
| abstract | The invention discloses red fluorescent powder excitated by near-ultraviolet broadband and a preparation method thereof. The chemical expression of the red fluorescent powder is R1R23-R32O3-3R4O3:xEu3+, wherein R1 is one, two or more of Y3+, La3+, Gd3+, Pr3+, Sm3+ and Bi3+, and R2 is one, two or three of Cl-, Br- and I-; R3 is one, two or more of La3+, Gd3+, Y3+, Pr3+, Sm3+, Bi3+, Tm3+ and Dy3+; R4 is W6+ or/and Mo6+; and x is equal to 0.005-2.0. The preparation process comprises the steps of preparing a raw material of powder, preparing a mixture material, prefiring, sintering and postprocessing. The red fluorescent powder presents broadband excitation and sharp peak transmission to near-ultraviolet light, and red has high luminescence intensity and good color purity. |
