Multiphase fluorescent ceramic material and preparation method thereof
The invention relates to the field of luminescent materials, in particular to a multiphase fluorescent ceramic material and a preparation method thereof, the chemical composition of the multiphase fluorescent ceramic material is xY2O3-yLu2O3-zAl2O3-mSiO2-nMgO-pRe2O3, x, y, z, m, n and p are mole percentages, and the sum of 2x and 2y and 2z and m and n and 2p is 100%. The emission spectrum of the fluorescent ceramic is in the 510-680nm waveband, the wavelength of the luminescence peak can be changed by adjusting the proportion of Y2O3, Lu2O3, Al2O3, MgO and SiO2 in the components, the change ofthe fluorescence emission peak from 520nm to 610nm can be realized, the luminescence efficiency is stable(greater than 80% at 200 DEG C)at high temperature, and the preparation method comprises the steps of medium-low temperature powder synthesis, large-size rapid molding, two-step sintering and aftertreatment. The problem that a single fluorescent transparent ceramic component spectrum lacks a red light component is solved through component regulation and control, high-quality and diversified selection is achieved for laser illumination and display, the design cost of a red light source is greatly reduced, beam homogenization and color diversification of the laser light source are better facilitated, and the method has important significance in actual production and application.
本发明涉及发光材料领域，具体涉及一种复相荧光陶瓷材料及其制备方法，所述复相荧光陶瓷材料的化学组成为xY2O3‑yLu2O3‑zAl2O3‑mSiO2‑nMgO‑pRe2O3，其中x、y、z、m、n、p为摩尔百分比，且2x+2y+2z+m+n+2p＝100％，该荧光陶瓷发射光谱在510‑680nm波段，其发光峰的波长可通过调节组分中Y2O3、Lu2O3、Al2O3、MgO和SiO2的比例进行改变，能实现从520nm‑610nm荧光发射峰的变化，且高温下其发光效率稳定(>80％@200℃)，其制备方法包括中低温合成粉体，大尺寸快速成型以及两步烧结和后处理等步骤。通过组分的调控解决了单一荧光透明陶瓷组分光谱缺少红光成分的问题，本发明为激光照明和显示实现高质量、多样化的选择，极大地降低了红光光源的设计成本、更利于激光光源光束均匀化和色彩多样化，对实际生产应用具有重要意义。
