Patent ID: 8741178

Claim:
A preparation method for blue light emitting glass, comprising following steps: weighting: weighing raw materials of CaCO 3 , Al 2 O 3 , SiO 2 and CeO 2 in accordance with a composition of aCaO.bAl 2 O 3 .cSiO 2 .xCe 2 O 3 ; wherein ranges of a, b, c and x are 15˜55 by mol part, 15˜35 by mol part, 20˜60 by mol part and 0.01˜5 by mol part, respectively; melting: mixing weighed raw materials uniformly and then melting the raw materials to obtain glass melt; molding: preserving the glass melt for 0.5˜3 h at a temperature at which the glass melt is obtained, then pouring the glass melt into a cast mold and pressing it to obtain the transparent glass; post-treating: preserving the transparent glass for 3˜20 h under reducing atmosphere at a temperature that has risen to 650˜1050° C., then cooling the transparent glass to room temperature and obtaining the blue light emitting glass.
