Abstract
A luminous nano-glass-ceramics used as white LED source and the preparing method of nano-glass-ceramics are provided. The glass is a kind of non-porous compact SiOglass in which luminous nano-microcrystalites are dispersed. The luminous nano-microcrystalite has the chemical formula of YGdAlO:Ce, wherein 0≦x≦3. The stability of the said glass is good and its irradiance is uniform. The preparing method comprises the following steps: dissolving the compound raw materials in the solvent to form mixed solution, dipping the nano-microporous SiOglass in the solution, taking it out and air drying, sintering at the temperature of 1100-1300° C. for 1-5 hours by stage heating, and obtaining the product. The method has a simple process, convenient operation and low cost.
