Novel red fluorescent ceramic wafer and preparation method thereof
The invention discloses a novel red fluorescent ceramic wafer and a preparation method thereof, and belongs to the technical field of luminescent material preparation and application. The chemical component is K2SiF6: xMn < 4 + >, x is the mass fraction, x is larger than 0 and smaller than or equal to 0.01, the fluorescent ceramic wafer is prepared through hot pressing, through doping under the Mn< 4 + > concentration limited by the invention, the luminescence loss during up-conversion and temperature rising is reduced, and particularly, the thermal stability is greatly improved under higherluminous flux. The product provided by the invention is stable in performance.
一种新型红色荧光陶瓷片及其制备方法,属于发光材料制备应用技术领域。化学组分为K2SiF6:xMn4+,其中x为质量分数,0<x≤0.01,采用热压制备了荧光陶瓷片,通过在本发明限定的Mn4+浓度下掺杂,降低了上转换和温度上升时的发光损失,特别是在更高的光通量下,大大提高了热稳定性。本发明提供的产品性能稳定。
