| titleOfInvention | A kind of oxynitride fluorescent powder and preparation method and the white LED light source containing the fluorescent material |
| abstract | The invention discloses a kind of oxynitride fluorescent powder and preparation method and the white LED light source containing the fluorescent material, its fluorescent material uses chemical general formula (Lu 1‑x Ce x )Al 5‑y Si y O 12‑4y/3 N z+4y/3 Represent, each parameter meets 0<It is 0 when x≤0.3,0≤y≤1.8,0≤z≤1.5, y is different with z；The initial feed used is pure zirconia lutetium, cerous nitrate, aluminum nitrate, silicon nitride/aluminium nitride and complexing agent citric acid.The silicon nitride is alpha content>95%th, oxygen content<2.0%th, the 13m of specific surface area 9 2 / g, 0.2 μm of average grain diameter submicron alpha Si 3 N 4 .Aluminium nitride is content >=99.9%, the submicron order F types AlN of 0.2 μm of average grain diameter.The fluorescent material of the present invention issues 15% that light intensity decays are no more than initial strength at 150 DEG C；It includes very wide excitation and emission spectra, can effectively be excited by 430 470nm blue light, send orange light of the peak wavelength scope in 500 625nm.In the LED chip for being coated onto InGaN bases, a kind of low colour temperature, high-color rendering, long-life, the warm white LED planar light source for being suitable for general room illumination are prepared for. |
