RED PHOSPHOR MATERIAL AND LIGHT-EMITTING DEVICE |
| 摘要 |
A red phosphor material comprising an essential component represented by a formula of ALn1-x-yEuxSmyM2O8 as a main component, where A represents at least one selected from Li, Na, and K; Ln represents at least one selected from La and Gd; M represents at least one selected from W and Mo; and x and y are numerical values that satisfy 0.1≦x+y≦0.7 and 0.005≦y≦0.08. A light-emitting device includes an excitation light source and the red phosphor material that absorbs excitation light emitted by the excitation light source and emits red light. |
