Fluorescent glass ceramic and preparation method thereof

The invention provides a novel YAG: Ce/LTA fluorescent powder/glass composite material (phosphorin glass, PiG) and a preparation method thereof, the PiG material is mixed according to the mass ratio of YAG: Ce = x LTA, and x is greater than or equal to 0.01 and less than or equal to 100. The preparation method of the PiG material comprises the following steps: mixing YAG: Ce fluorescent powder andthe LTA molecular sieve according to a certain mass ratio; then adding absolute ethyl alcohol, and fully and uniformly mixing through a planetary ball mill; drying an obtained slurry to obtain powder, directly putting the powder into a box-type furnace for sintering, heating the LTA molecular sieve at high temperature to form glass, and uniformly embedding YAG: Ce fluorescent powder into the glass to obtain the YAG: Ce/LTA PiG material. The preparation method disclosed by the invention has the advantages of simple preparation process, low cost, no toxicity in the preparation process and the like, and the PiG material
