Red emitting phosphor with slow exponential decay |
| 摘要 |
A luminescent phosphor composition having enhanced luminescent decay lifetime consists essentially of a non-stoichiometric cerium and manganese coactivated alkaline earth orthophosphate represented by the formula Sr(3-v-w-x-y-z) &squ& vMgwCAx(PO4)2:CeyMnz where 0.001</=v</=0.05 0.180</=w</=0.35 0</=x</=0.08 0.015</=y</=0.05 0.01</=z</=0.10. An improved fluorescent lamp employing the disclosed phosphor is also described.
