Fluorescent ceramic as well as preparation method and application thereof
The invention discloses fluorescent ceramic as well as a preparation method and application thereof. The fluorescent ceramic is selected from at least one of substances with a composition general formula shown in a formula I, and the formula I is Lu<3-x-y>CeMAl<5-y>QO12, wherein M represents a first co-doped element, the first co-doped element is selected from at least one of alkaline earth metal elements, Q represents a second co-doped element, the second co-doped element is selected from at least one of a Si element and a Ge element, x is more than or equal to 0.0001 and less than or equal to 0.3, and y is more than or equal to 0 and less than or equal to 2. Charge balance is realized through equivalent common doping of doped M<2+> and Q<4+> ions, so that variable-valence Ce<3+>ions in the fluorescent ceramic are inhibited from being converted into Ce<4+> ions, and the fluorescent ceramic is mostly composed of Ce<3+> light-emitting ions. The fluorescent ceramic has the characteristics of high density, good laser saturation performance, high luminous efficiency and the like, can be used as a key material of a color converter, and has a huge application potential in the field of high-power laser illumination.
本申请公开了一种荧光陶瓷及其制备方法与应用，所述荧光陶瓷选自具有式Ⅰ所示组成通式的物质中的至少一种；Lu3‑x‑yCexMyAl5‑yQyO12式Ⅰ；其中，M表示第一共掺元素，所述第一共掺元素选自碱土金属元素中的至少一种；Q表示第二共掺元素，所述第二共掺元素选自Si元素、Ge元素中的至少一种；x的取值范围为0.0001≤x≤0.3；y的取值范围为0≤y≤2。本申请通过掺杂M2+和Q4+离子等量共同掺杂作用实现电荷平衡，使得荧光陶瓷中可变价的Ce3+离子被抑制转变为Ce4+，因此所述荧光陶瓷组成中大部分为Ce3+发光离子。该荧光陶瓷具有密度高、激光饱和性能好、发光效率高等特点，可用作颜色转换器的关键材料，在大功率激光照明领域具有巨大的应用潜力。
