Abstract Phosphor-glass composites (PGC) are excellent candidates for highly efficient and stable photonic converters; however, their synthesis generally requires harsh procedures long time, resulting in additional performance loss energy consumption. Here we develop a rapid synthetic route to PGC within about 10 seconds, which enables uniform dispersion of Y 3 Al 5 O 12 :Ce 3+ (YAG:Ce) phosphor particles through particle self-stabilization model molten tellurite glass.
