Calcium fluoride-based fluorescent ceramic material and preparation method thereof
The invention relates to a calcium fluoride-based fluorescent ceramic material and a preparation method thereof, and the calcium fluoride-based fluorescent ceramic material comprises 94-99% by weight of a calcium fluoride matrix and 1-6% by weight of fluorescent powder. The sintering temperature of the calcium fluoride-based fluorescent ceramic is greatly reduced by adopting an ultralow-temperature sintering technology, the light-emitting characteristic of commercial fluorescent powder can be effectively retained, the luminous efficiency and the color rendering index of a ceramic-based LED device are greatly improved, and the heat resistance and the stability of the fluorescent ceramic are effectively improved.
本发明涉及一种氟化钙基荧光陶瓷材料及其制备方法，按照重量百分比，由94～99％氟化钙基体和1～6％的荧光粉组成。本发明采用的超低温烧结技术极大地降低了氟化钙基荧光陶瓷的烧结温度，可以有效的保留商用荧光粉的发光特性，大幅度的提高了陶瓷基LED器件的光效和显色指数，并且有效提升了荧光陶瓷的耐热性和稳定性。
