Composite structure fluorescent ceramic and preparation method thereof
The invention discloses a composite structure fluorescent ceramic and a preparation method thereof, and relates to the technical field of luminescent materials. The composite structure fluorescent ceramic comprises Al2O3-YAG: Ce composite ceramic and YAG transparent ceramic which are arranged up and down, and edge-covered Al2O3 ceramic; the preparation method comprises the following steps: respectively mixing Al2O3-YAG: Ce and YAG ceramic raw materials, pressing together to obtain a biscuit, sintering the biscuit, preserving heat, and cutting to obtain the chip-level Al2O3-YAG: Ce/YAG composite fluorescent ceramic. And pressing the Al2O3 powder and the chip-scale composite fluorescent ceramic together to obtain a biscuit, and sintering and preserving heat of the biscuit to obtain the Al2O3-YAG: Ce/YAG/Al2O3 composite structure fluorescent ceramic. The fluorescent ceramic designed by the invention is high in luminous efficiency, good in heat dissipation performance, high in saturation power density and suitable for a transmission-type laser lighting system; in addition, the annealing process of the fluorescent ceramic and the sintering process of the aluminum oxide ceramic are combined into one, and the preparation process is simple and suitable for industrialization.
本发明公开的一种复合结构荧光陶瓷及制备方法，涉及发光材料技术领域。复合结构荧光陶瓷包括上下设置的Al2O3‑YAG:Ce复相陶瓷和YAG透明陶瓷以及包边的Al2O3陶瓷；将Al2O3‑YAG:Ce、YAG陶瓷原料分别进行混合，一起压制成素坯，将素坯进行烧结保温、裁剪得到芯片级Al2O3‑YAG:Ce/YAG复合荧光陶瓷；将Al2O3粉体、芯片级复合荧光陶瓷一起压制成素坯，将素坯进行烧结保温，得到Al2O3‑YAG:Ce/YAG/Al2O3复合结构荧光陶瓷。本发明设计的荧光陶瓷发光效率高、散热性能好、饱和功率密度高，适合透射式激光照明系统；此外，将荧光陶瓷的退火过程与氧化铝陶瓷的烧结过程合二为一，制备工艺简单，适合产业化。
