Abstract: The present disclosure is related to a fluorescent glass for a light emitting diode and a manufacturing method thereof. The fluorescent glass for the light emitting diode includes a glass powder and a fluorescent powder, wherein the glass powder and the fluorescent powder are mixed to form a fluorescent glass, the material for manufacturing the glass powder comprises silicon dioxide with 20 wt % to 37 wt %, diboron trioxide with 31 wt %-47 wt % and calcium oxide with 16 wt %˜35 wt %, and the material of the fluorescent powder is selected from one of Ce-YAG, LuAG, silicate, and nitrides/oxynitrides fluorescent powder. The fluorescent glass of the present disclosure is formed by mixing and sintering the glass powder and the fluorescent powder and has low sintering temperature, so as to avoid the deterioration of color of the fluorescent powder due to high temperature. Therefore, the fluorescent glass of the present disclosure has good transparency, and the light emitting diode applying this fluorescent glass has good lighting efficiency.
