Composite fluorescent ceramic for reflection type laser illumination and preparation method of composite fluorescent ceramic
The invention discloses a reflective composite fluorescent ceramic for laser illumination and a preparation method thereof. The method comprises the following steps: S1, respectively preparing YAG powder, YAG: Ce powder and YAG-Al2O3 powder; s2, pressing a YAG/YAG: Ce/YAG-Al2O3 composite ceramic biscuit by adopting dry pressing molding, and carrying out vacuum sintering and annealing; and S3, laser engraving is adopted to form a conical structure array at the YAG position on the surface of the composite ceramic, and finally the thickness of the composite fluorescent ceramic is 4-5 mm. As a luminescent material, the composite fluorescent ceramic for reflective laser illumination prepared by the preparation method disclosed by the invention has the advantages of high thermal conductivity, high luminous efficiency and low incident light surface temperature.
本发明公开了一种反射式激光照明用复合荧光陶瓷及其制备方法，该方法包括：S1：分别制备YAG粉体、YAG:Ce粉体和YAG‑Al2O3粉体；S2：采用干压成型压制YAG/YAG:Ce/YAG‑Al2O3复合陶瓷素坯，进行真空烧结和退火；S3：采用激光雕刻在复合陶瓷表面YAG处形成圆锥形结构阵列，最终复合荧光陶瓷厚度为4～5mm。本发明制备方法制得的反射式激光照明用复合荧光陶瓷作为发光材料具有热导率高、发光效率高、入射光表面温度低的优点。
