High-thermal-stability high-color-rendering-index fluorescent ceramic for white light LED/LD and preparation method of fluorescent ceramic
The invention discloses high-thermal-stability high-color-rendering-index fluorescent ceramic for white light LED/LD and a preparation method of fluorescent ceramic. The chemical formula of the fluorescent ceramic is (TbyCexY1-x-y)3(MnzAl1z)5O12, x is the molar percentage of Ce<3+> doped for replacing Y<3+>, y is the molar percentage of Tb<3+> doped for replacing Y<3+>, z is the molar percentage of Mn<2+> doped for replacing octahedron Al<3+>, x is larger than or equal to 0.0025 and less than or equal to 0.02, y is larger than 0 and less than or equal to 0.2, z is larger than or equal to 0.005and less than or equal to 0.01, y:x is equal to (10-25):1, and the fluorescent ceramic is prepared through solid-phase reaction sintering. The main emission spectrum peak of the transparent fluorescent ceramic material ranges from 541 nm to 560 nm, the full width at half maximum ranges from 88 nm to 105 nm, emission from cold white light to warm white light can be achieved under excitation of a high-power blue light LED (350 mA to 1000 mA) or blue light LD (2 W to 10 W), the color temperature ranges from 3800 K to 7000 K, and the color rendering index ranges from 70 to 80. The luminescent intensity is attenuated by 10%-15% at 150 DEG C, the thermal stability is high, the preparation process of the ceramic is simple, and industrial production is easy.
