| 摘要 |
The present invention provides a method for manufacturing a luminescent material whereby the surfaces of phosphor particles are uniformly coated with glass, and a luminescent material made up of such particles is easily obtainable, a luminescent material manufactured by the manufacturing method, and a display substrate and a display apparatus having the luminescent material. The luminescent material is manufactured through the steps of adding a phosphor in the form of a solid solution comprising a sulfide or an oxysulfide, and a luminescent center substance incorporated in the sulfide or the oxysulfide in an aqueous solution containing water glass with stirring; adding the resulting aqueous solution to an aqueous solution of a metallic salt with stirring; forcedly extracting particles of the phosphor from the resulting aqueous solution; and drying the particles of the phosphor extracted. The display substrate and the display apparatus are obtained by applying the luminescent material onto a glass plate or the like. |
