PHOSPHOR |
| 摘要 |
A phosphor, having a general formula of K2[Si1-xGex]yF6:Mn1-y4+. The phosphor is excited to emit a light having a first main emission peak with a first maximum emission intensity and a first dominant wavelength, wherein a relative emission intensity S of the light of the phosphor is constantly greater than 85% across an temperature of the phosphor between 300 K and 470 K during operation, wherein S=(IT/IRT)*100%, IRT and IT are the first maximum emission intensity when the temperature of the phosphor is at 300 K and T during operation respectively, and 300 K<T≦470K. |
