Fluorescent ceramic as well as preparation method and application thereof
The invention provides fluorescent ceramic as well as a preparation method and application thereof. According to the fluorescent ceramic, a whisker structure is distributed in the fluorescent ceramic, the whisker length of the whisker structure is 5-20 microns, and the distribution mass ratio of the whisker structure in the fluorescent ceramic is 2-6%. The crystal whisker structure is at least one of aluminum nitride crystal whiskers or aluminum oxide crystal whiskers. A certain proportion of whiskers are introduced into the fluorescent ceramic, on one hand, the heat conduction performance of the fluorescent ceramic is effectively improved through the whisker structure, heat conduction and heat dissipation can be more rapidly achieved, and the mechanical strength of the fluorescent ceramic is also improved through the whisker structure; on the other hand, the fine grain particles are introduced, the fine grain particles can well exert refraction and scattering of light, meanwhile, the crystal whisker structure and the fine grain particles can cooperate with each other, refraction and scattering of light in the fluorescent ceramic are further improved, the homogenization effect of a light field is enhanced, and meanwhile the lighting effect is improved.
本发明提供了一种荧光陶瓷及其制备方法与应用。所述荧光陶瓷，在荧光陶瓷内部分布有晶须结构，所述晶须结构的晶须长度为5‑20μm，所述晶须结构在荧光陶瓷中的分布质量占比为2‑6%。所述的晶须结构为氮化铝晶须或氧化铝晶须中的至少一种。通过在荧光陶瓷中引入一定比例的晶须，一方面，利用晶须结构有效提升了荧光陶瓷的导热性能，能够实现更加迅速的导热散热，而晶须结构也增加了荧光陶瓷的机械强度；另一方面，本发明通过引入细晶颗粒，细晶颗粒能够很好地发挥光的折射与散射，同时，晶须结构能够与细晶颗粒相互协同配合，进一步提升光在荧光陶瓷内部的折射与散射，增强了光场的匀化作用，同时提升了光效。
