| 摘要 |
The present invention relates to the synthesis of a fluorescent body, wherein an oxide, carbonate, nitride, boride, carbide or sulphide of a periodic table element or a mixture of two or more of the same in the form of a powder is subjected to high-temperature melting and to rapid cooling by a method such as gas spraying, thereby producing an amorphous fluorescent material which is then subjected to a heat treatment such that the whole is amorphous or some or all of the amorphous form is crystallised. |
