Abstract
The present disclosure provides a wavelength conversion glass, a method for manufacturing the wavelength conversion glass, and a light emitting device including the wavelength conversion glass. The wavelength conversion glass includes a TeO2—B2O3—ZnO—BaO-based transparent glass containing tellurium dioxide (TeO2), boric oxide (B2O3), zinc oxide (ZnO), and barium oxide (BaO); and phosphor micro-particles dispersed in the transparent glass.
Claims5
A method for producing a wavelength conversion glass, the method comprising:
- providing a wavelength conversion glass frit composition containing TeO2, B2O3, ZnO, and BaO;
- firing the wavelength conversion glass frit composition at a glass frit firing temperature;
- pulverizing the fired wavelength conversion glass frit composition to form TeO2—B2O3—ZnO—BaO-based glass frits;
- mixing the TeO2—B2O3—ZnO—BaO-based glass fits with phosphor powders, to form a wavelength conversion glass composition;
- and
- firing the wavelength conversion glass composition at a wavelength conversion glass firing temperature, to form a wavelength conversion glass, wherein the wavelength conversion glass has phosphor micro-particles dispersed therein, and wherein the wavelength conversion glass firing temperature is lower than the glass frit firing temperature.
