Manufacture of a phosphor composition with hematite |
摘要 |
A method of manufacturing a phosphor composition of a phosphor comprising a pigment coating of hematite, includes a first step in which the phosphor is coated with an iron-containing starting compound for hematite, and a second step, in which the phosphor with the coating is calcined, thereby converting the iron-containing starting compound for hematite into hematite. The calcining operation is carried out in an atmosphere of a gas mixture of water vapor and an oxidizing gas.
