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 SiO 2 glass in which luminous nano-microcrystallites are dispersed. The luminous nano-microcrystalite has the chemical formula of Y x Gd 3-x Al 5 O 12 :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 SiO 2 glass 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.
