| 简介 |
PURPOSE : A silicate glass manufacturing method including lead sulfide quantum dot containing rare earth are provided to control size of quantum dots by adding rare earth compound to inside a silicate glass without adjusting heat treatment temperature or time. CONSTITUTION : A manufacturing method of silicate glasses comprises the following steps : manufacturing a base mixture by mixing silicon oxide with rare earth oxide which includes red compound and sulfur compound; manufacturing a silicate glass molten product by fusing the base mixture; manufacturing the silicate glass by cooling the silicate glass molten material; and segregating lead sulfide quantum dots by heat treating the silicate glass; and completing the silicate glass which includes the lead sulfide quantum dot including the rare earth metals. [Reference numerals] (S100) Manufacturing silicon oxide which includes lead compound and sulfur compound; (S200) Preparing rare earth compound; (S300) Manufacturing a base mixture by mixing silicon oxide with the lead oxide; (S400) Manufacturing the silicate glass by fusing the base mixture; (S500) Manufacturing the silicate glass by cooling the silicate glass molten material; (S520) Annealing silicate glass; (S600) Segregating lead sulfide quantum dots by heat treating the silicate glass; (S700) Completing the silicate glass which includes the lead sulfide quantum dot |
