The invention discloses a fluorescent ceramic processed by a femtosecond laser texturing technology, which is prepared by the following method: weighing initial raw materials according to the stoichiometric ratio of each element in the general formula (Ce 0.001 PrxY 0.009-x) 3Al5O12, wherein x is greater than 0.001 and less than or equal to 0.005, ball-milling and mixing the initial raw materials, a dispersant polyetherimide and absolute ethyl alcohol, drying the ball-milled mixed slurry, sieving and calcining, performing dry pressing on the calcined mixed powder, sintering the pressed materials under the vacuum condition, grinding and polishing after the materials are cooled, obtaining fluorescent ceramic, texturing on the surface and the interior of the prepared fluorescent ceramic through auxiliary materials and laser, and obtaining the fluorescent ceramic. The invention provides the fluorescent ceramic processed by using the femtosecond laser texturing technology, and compared with the original fluorescent ceramic, the light uniformity is better, and the optical property is more excellent.
本发明公开了一种用飞秒激光织构化技术加工的荧光陶瓷，采用以下方法制备得到：先按照通式(Ce0.001PrxY0.009‑x)3Al5O12，0.001＜x≤0.005中各元素的化学计量比称取初始原料，将初始原料、分散剂聚醚酰亚胺与无水乙醇进行球磨混合，球磨后的混合浆料经干燥、过筛后进行煅烧，将煅烧后的混合粉体进行干压，压制后的物料放在真空条件下进行烧结，待冷却取出后打磨、抛光，得到荧光陶瓷，用辅助材料和激光在制好的荧光陶瓷表面和内部进行织构，即可。本发明提供了一种用飞秒激光织构化技术加工的荧光陶瓷，相比原来的荧光陶瓷，光均匀性更好，其具有更加优良的光学性质。
