Preparation method and application of europium ion activated silicate luminescent ceramic
The invention discloses a preparation method and application of europium ion activated silicate optical ceramic, and belongs to the technical field of optical ceramic. The general chemical formula of the optical ceramic is Na2Ca3 (1-x) EuxSi3O10, the matrix is silicate, x is the doping molar ratio of activating agent Eu < 3 + > ions, and x is larger than or equal to 0.005 and smaller than or equal to 0.3. The preparation method of the optical 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 ceramic. The obtained optical ceramic emits-620 nm red light under excitation of near ultraviolet light, and can be used for manufacturing white light LED devices excited by near ultraviolet chips. The silicate optical ceramic is simple to prepare and low in production cost.
本发明公开了一种铕离子激活的硅酸盐光学陶瓷制备方法与应用，属于光学陶瓷技术领域。该光学陶瓷的化学通式为Na2Ca3(1‑x)EuxSi3O10其中基质为硅酸盐，x为激活剂Eu3+离子的掺杂摩尔比,0.005≤x≤0.3。该光学陶瓷制备步骤为：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陶瓷。得到的光学陶瓷在近紫外光的激发下发射出~620纳米的红色发光，可以用来制造近紫外芯片激发的白光LED器件。本发明的硅酸盐光学陶瓷制备简单、生产成本低。
