Gradient-concentration-change fluorescent ceramic for laser illumination, and preparation method thereof
The invention discloses a gradient-concentration-change fluorescent ceramic for laser illumination, and a preparation method thereof, wherein the fluorescent ceramic uses a YAG ceramic as a matrix material, uses Ce<3+> ions as light-emitting ions, and has a molecular formula of Cex:Y3-xAl5O12, x is larger than or equal to 0 and smaller than or equal to 0.06, and the fluorescent ceramic is distributed in the excitation incident direction of a laser light source in the mode that the concentration is gradually increased. According to the invention, laser energy can be uniformly absorbed and excited, so that the temperature of the material is uniform, the problems of fluorescence conversion efficiency reduction and sample explosion caused by temperature difference of the material are solved, the fluorescence spectrum is widened by utilizing the gradient concentration change, and the color rendering index of the fluorescent ceramic is improved.
本发明公开激光照明用浓度渐变荧光陶瓷及其制备方法，所述荧光陶瓷以YAG陶瓷作为基质材料，Ce离子作为发光离子，其分子式为Ce:YAlO，x的取值范围：0≤x≤0.06，所述荧光陶瓷沿激光光源激发入射方向上呈浓度渐变升高分布。本发明的有益效果在于：能够均匀地吸收激发激光能量，从而实现材料温度均匀，解决材料因温差导致的荧光转化效率降低及样品炸裂问题，并且利用渐变浓度对荧光光谱拓宽，提高荧光陶瓷显色指数。
