Fluorescent ceramic with adjustable light-emitting color and preparation method thereof
The invention provides a light-emitting color adjustable Ce<3+> and Mn<2+> co-doped LuAG fluorescent ceramic material and a preparation method thereof. The chemical formula of the fluorescent ceramicmaterial is Lu3-x-yCexMnyAl5-ySiyO12, x is equal to 0.015, and y is greater than or equal to 0 and less than or equal to 0.1. The preparation method of the fluorescent ceramic material comprises the following steps of proportioning lutetium oxide, aluminum oxide, cerium oxide, manganese oxide and silicon oxide raw materials according to the chemical formula Lu3-x-yCexMnyAl5-ySiyO12, carrying out uniaxial pressing-cold isostatic pressing on the proportioned powder to obtain a biscuit, sintering the biscuit in a tubular furnace or box type furnace filled with a flowing oxygen atmosphere, and annealing in a hydrogen-nitrogen mixed atmosphere to finally obtain the Lu3-x-yCexMnyAl5-ySiyO12 fluorescent ceramic material. The fluorescent ceramic provided by the invention has excellent thermal stability, high luminous efficiency and fluorescent luminous color adjustability, and the corresponding preparation method has the advantages of simple process, low cost and the like.
本发明提供了一种发光颜色可调Ce3+，Mn2+共掺LuAG荧光陶瓷材料及其制备方法，该荧光陶瓷材料的化学式为Lu3‑x‑yCexMnyAl5‑ySiyO12，其中：x＝0.015，0≤y≤0.1。该荧光陶瓷材料的制备方法为：将氧化镥，氧化铝，氧化铈，氧化锰，氧化硅原料按照化学式Lu3‑x‑yCexMnyAl5‑ySiyO12进行配比，将配好的粉体经单轴压‑冷等静压压制成素坯，然后将素坯在通有流动氧气气氛的管式炉或箱式炉中烧结，再在氢氮混合气氛中退火，最终获得Lu3‑x‑yCexMnyAl5‑ySiyO12荧光陶瓷材料。本发明所提供的荧光陶瓷具有优异的热稳定性、高的发光效率和荧光发光颜色可调控性，相应的制备方法具有工艺简单、低成本等优点。
