Fluorescent ceramic having surface artificial microstructure and used for white-light laser illumination, and preparation method thereof
The invention discloses fluorescent ceramic having a surface artificial microstructure and used for white-light laser illumination, and a preparation method thereof, wherein the chemical composition of the fluorescent ceramic is (Ce[x]M[y]Y[1-x-y])3Al5O12, M is one or more of Gd, La, Pr, Sm, Tb and Lu, x is larger than or equal to 0.001 and smaller than or equal to 0.03, y is larger than or equalto 0 and smaller than or equal to 1, and an artificial microstructure is formed on at least one surface of the fluorescent ceramic. The fluorescent ceramic provided by the invention has the beneficialeffect that a blue laser semiconductor is used as a laser light source to obtain white light, and the problems that a light spot center area is white and a surrounding area is yellow in a laser lighting product can be solved by designing a surface microstructure.
本发明公开用于一种白光激光照明用具有表面人工微结构的荧光陶瓷及其制备方法，所述荧光陶瓷的化学组成为：(CeMY)AlO，其中，M为Gd、La、Pr、Sm、Tb、Lu中的一种或多种，x的取值范围为：0.001≤x≤0.03，y的取值范围为：0≤y≤1；所述荧光陶瓷中至少有一表面上形成有人工微结构。本发明的有益效果在于：本发明提供的荧光陶瓷能够使用蓝光激光半导体作为激光光源获得白光。本发明提供的荧光陶瓷通过对表面微结构的设计能够解决激光照明产品中光斑中心区域“白”，周围区域“黄”的问题。
