Fluorescent ceramic and preparation method thereof
The invention discloses fluorescent ceramic and a preparation method thereof. The fluorescent ceramic is selected from at least one of substances in a chemical formula shown in a formula I in the specification. The fluorescent ceramic has excellent light-emitting thermal stability and mechanical properties, the problem of low color rendering index caused by reduction of green light intensity at high temperature is solved, so that a light source with higher brightness and more stable color quality is obtained, the preparation method can be used for directly preparing the annular fluorescent ceramic chip, the preparation period is greatly shortened, the production efficiency is improved, and the production cost is reduced. And the preparation cost and the processing cost are reduced.
本申请公开了一种荧光陶瓷及其制备方法，该荧光陶瓷选自具有式Ⅰ所示化学式中的物质中的至少一种。该荧光陶瓷具有优异的发光热稳定性和机械力学性能，解决了高温时绿光强度降低造成的显色指数低的问题，从而得到亮度更高、色彩品质更稳定的光源，该制备方法可直接制备出环状的荧光陶瓷片，大大缩短制备周期，提高了生产效率，降低了制备成本及加工成本。
