PURPOSE: The manufacturing method of the ratio visible luminous body.In the SrB4O7:Ag fluorescent substance, "the luminous body suitable to use as the fluorescent substance for forgery and check protect" can be manufactured as elevation. CONSTITUTION: Following chemical formula: the manufacturing method of ratio visible luminous body marked as the Sr (1-x-y) B 4O 7:Ag.Falling stages are included :Step of mixing the strontium[strontium]compound, the boric acid[boric acid](H3BO3), and 1 is the silver[monovalent silver]compound and alkali metal salt compound.The step of plasticizing under atmosphere mixture.And the step of shattering to pieces mixture it cools to the room temperature the mixture plasticized as described above. In the chemical formula, M the alkali metal..0<x<1, 0<y<1 and 0<x+y<1.1 as to the argentous compound, is the silver oxide[silver oxide](Ag2O) or the silver nitrate[silver nitrate](AgNO3). |
