一种微晶玻璃及其制备方法和应用
摘要：
本发明提供一种微晶玻璃及其制备方法和应用，该微晶玻璃在氧化物玻璃基体中镶嵌了Ce:YAG和Eu:CaAlSiN3两种荧光微晶，该微晶玻璃中的玻璃组分和摩尔百分含量为：1-20mol％SiO2；1-50mol％P2O5；1-20mol％Na2O；1-15mol％B2O3；1-20mol％BaO；1-20mol％SrO；1-20mol％CaO；1-30mol％Al2O3；1-10mol％La2O3；Ce:YAG微晶的含量为氧化物玻璃基体的1-20wt％；Eu:CaAlSiN3微晶的含量为氧化物玻璃基体的1-10wt％。本发明的微晶玻璃在蓝光激发下发射波段覆盖黄光和红光区域，黄光、红光和蓝光组合能产生高显色指数的白光，因而可用于组建高显色指数的蓝光芯片激发的白光LED。
摘要（英）：

The invention provides microcrystalline glass and a preparation method and application thereof. According to the microcrystalline glass, two kinds of fluorescent microcrystals including Ce:YAG and Eu:CaAlSiN3 are embedded in an oxide glass substrate, wherein the microcrystalline glass comprises glass components including, by mole percent, 1-20 mol% of SiO2, 1-50 mol% of P2O5, 1-20 mol% of Na2O, 1-15 mol% of B2O3, 1-20 mol% of BaO, 1-20 mol% of SrO, 1-20 mol% of CaO, 1-30 mol% of Al2O3 and 1-10 mol% of La2O3, the content of the Ce:YAG microcrystals is 1-20 wt% of the oxide glass substrate, andthe content of the Eu:CaAlSiN3 microcrystals is 1-10 wt% of the oxide glass substrate. The emission waveband of the microcrystalline glass covers a yellow light area and a red light area under the excitation of blue light, and yellow light, red light and the blue light can be combined to generate white light high in color rendering index so that the microcrystalline glass can be used for establishing a white light LED which is excited by a blue light chip and has a high color rendering index.
