Preparation method and application of cerium ion activated phosphate luminescent ceramic
The invention discloses a preparation method and application of cerium ion activated phosphate optical engineering ceramic, and belongs to the technical field of optical engineering ceramic. The general chemical formula of the optical engineering ceramic is NaSrLa1-xCex(PO4)2, wherein a matrix is phosphate, x is the doping molar ratio of an activator Ce 3+ ion, and x is greater than or equal to 0.015 and less than or equal to 0.3. The preparation method of the optical engineering ceramic comprises the following steps: firstly, preparing ceramic powder by adopting a chemical sol-gel method, then, carrying out net size forming on the ceramic powder by adopting dry pressing and isostatic pressing methods, and finally, carrying out solid-phase sintering to obtain the final optical engineering ceramic. The optical engineering ceramic emits blue light of 460 nanometers under excitation of near ultraviolet light, and can be used for manufacturing white light LED devices excited by near ultraviolet chips or used for nondestructive optical detection of engineering ceramic defects. According to the invention, the phosphate optical engineering ceramic is simple to prepare and low in production cost.
本发明公开了一种铈离子激活的磷酸盐光学工程陶瓷制备方法与应用，属于光学工程陶瓷技术领域。该光学工程陶瓷的化学通式为NaSrLa1‑xCex(PO4)2，其中基质为磷酸盐，x为激活剂Ce3+离子的掺杂摩尔比,0.015≤x≤0.3。该光学工程陶瓷制备步骤为：先采用化学溶胶‑凝胶法制备陶瓷粉体，再采用干压、等静压方法进行陶瓷粉体净尺寸成型，最后进行固相烧结得到最终光学工程陶瓷。得到的光学工程陶瓷在近紫外光的激发下发射出~460纳米的蓝色发光，可以用来制造近紫外芯片激发的白光LED器件或用于工程陶瓷缺陷的无损光学检测方面。本发明的磷酸盐光学工程陶瓷制备简单、生产成本低。
