Abstract

The invention relates to the field of luminescent materials, in particular to a composite fluorescent ceramic material and a preparation method thereof. The chemical composition of the composite fluorescent ceramic material is xY 2 o 3 ‑yLu 2 o 3 ‑zAl 2 o 3 ‑mSiO 2 ‑nMgO‑pRe 2 o 3 , where x, y, z, m, n, p are mole percentages, and 2x+2y+2z+m+n+2p=100%, the fluorescent ceramic emission spectrum is in the 510-680nm band, and the wavelength of its luminescence peak can be By adjusting Y in the component 2 o 3 、Lu 2 o 3 、Al 2 o 3 , MgO and SiO 2 Change the ratio of the fluorescent emission peak from 520nm to 610nm, and its luminous efficiency is stable at high temperature (>80%@200℃). Sintering and post-processing steps. The problem of the lack of red light components in the spectrum of a single fluorescent transparent ceramic component is solved through the regulation of the components. The invention realizes high-quality and diversified choices for laser lighting and display, greatly reduces the design cost of the red light source, and is more conducive to The homogenization and color diversification of laser light source beams are of great significance to practical production applications.
