| titleOfInvention | A kind of Eu3+ activated red light-emitting phosphor and its preparation method and application |
| abstract | An Eu 3+ activated red light-emitting phosphor, preparation method and application thereof, the chemical formula is: Bi 2 (La 2 Y 0.4 Ca 0.6 Gd 1-x Eu x )O 8.7 , where x is Eu 3+ doped Gd 3 The molar ratio of + positions, 0.01≤x≤0.6. The host lattice in the present invention is Bi 2 (La 2 Y 0.4 Ca 0.6 Gd)O 8.7 . On the premise of maintaining a single phase, complex cation replacement is implemented based on the same lattice site, so that the lattice site is The doped Eu 3+ environment is sufficiently disturbed to obtain pure red luminescence with good chromaticity and high luminous efficiency; the phosphor powder has a wide excitation band in the ultraviolet-near-ultraviolet region, and can be obtained under the excitation of ultraviolet-near-ultraviolet wavelengths. The red luminescence is a sharp jump emission peak at 611nm, which is widely used in luminescent lighting and display devices. The high-temperature solid-phase method is adopted in the preparation, and the method is simple and easy to implement, the raw materials are readily available, and there is no pollution. |
