Preparation method of composite fluorescent ceramic
The invention discloses a preparation method of composite fluorescent ceramic, and relates to the technical field of laser illumination. The composite fluorescent ceramic is composed of Ce: YAG fluorescent ceramic and a YAG transparent ceramic chip from top to bottom. The preparation method comprises the following steps: firstly, preparing the YAG transparent ceramic wafer; secondly, preparing a Ce: YAG tape casting biscuit; and finally, combining the Ce: YAG tape-casting biscuit with the YAG transparent ceramic wafer up and down, and sintering in a vacuum sintering furnace. According to the invention, the Ce: YAG casting biscuit is sintered on the YAG transparent ceramic chip by adopting a co-firing scheme, and is tightly bonded with the heat dissipation substrate, so that the heat dissipation performance is excellent, and the luminescence is stable; meanwhile, the size of the fluorescent ceramic is in the millimeter level, the light emitting area is smaller, the brightness is higher, and the light shaping difficulty is lower.
本发明公开的一种复合荧光陶瓷制备方法，涉及激光照明技术领域。所述复合荧光陶瓷由Ce:YAG荧光陶瓷和YAG透明陶瓷片上下组成；制备方法：首先制备YAG透明陶瓷片；其次制备Ce:YAG流延素坯；最后将Ce:YAG流延素坯与YAG透明陶瓷片上下组合，放入真空烧结炉中进行烧结。本发明采用共烧方案将Ce:YAG流延素坯烧结在YAG透明陶瓷片上，与散热基底黏合紧密，散热性能极佳，发光稳定；同时荧光陶瓷尺寸为毫米级别，具有更小的发光面积，亮度更高，光整形难度更低。
