Phosphor, light-emitting device including said phosphor, projector, head-up display and vehicle including said light-emitting device |
摘要 |
A phosphor includes a host crystal including Sr3MgSi2O8 crystal and SrMgSiO4 crystal and also includes Eu2+, or Eu2+ and Mn2+ as luminescent centers. Alternatively, a phosphor includes a host crystal including Sr3MgSi2O8 crystal and SrMgSiO4 and also includes Eu2+ as a luminescent center, the phosphor being free from Mn2+ as a luminescent center. A light-emitting device includes a phosphor layer containing the phosphor. A projector and a vehicle include the light-emitting device. |
