| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide coated phosphor particles which avoid the aggregation of the phosphor, have good gas barrier property and can enhance the durability of a semiconductor light emitting device, and a phosphor-containing composition. <P>SOLUTION: The coated phosphor particles are obtained by coating (A) phosphor particles with a glass composition containing one or more metals selected from alkali metals, alkaline earth metals and Zn, wherein the glass composition has a yield point of ≤800°C and/or a thickness of a coating layer which the glass composition forms is 0.1-10 μm. <P>COPYRIGHT: (C)2009,JPO&INPIT |
